And the article contained the following:

Co-Zn/NC was prepared by a sacrificial template self-reduction method with zeolitic imidazolate frame-8 (ZIF-8) impregnating the Co2+ as the precursor. At 125°C for 2.5 h, furfural was completely converted to furan-2-ylmethanol (FM) over Co17Zn/NC600, while FM selectivity over Co/NC600 is only 70.6%. According to multiple characterizations, Co17Zn/NC600 (Co loading 17%, calcined at 600°C) consists of flower-like spherical Co3ZnC nanoparticles (NPsCo3ZnC) uniformly distributed on its surface. The NPsCo3ZnC are the main active ingredients for highly selective furfural hydrogenation to FM, which is confirmed by furfural hydrogenation over Co-Zn/NC prepared with different Co loadings and different calcination temperatures The excellent activity and stability of Co17Zn/NC600 were confirmed by recycling experiment and furfural conversion is still above 90% after repeated use of Co17Zn/NC600 for 8 cycles. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Reference of Pentane-1,5-diol

On April 30, 2020, Li, Xuemei; Tian, Junying; Liu, Hailong; Tang, Congkui; Xia, Chungu; Chen, Jing; Huang, Zhiwei published an article.Computed Properties of 111-29-5 The title of the article was Effective synthesis of 5-amino-1-pentanol by reductive amination of biomass-derived 2-hydroxytetrahydropyran over supported Ni catalysts. And the article contained the following:

A highly efficient and green process was developed for the synthesis of useful 5-amino-1-pentanol (5-AP) from biomass-derived dihydropyran by coupling the in situ generation of 5-hydroxypentanal (5-HP, via the ring-opening tautomerization of 2-hydroxytetrahydropyran (2-HTHP)) and its reductive amination over supported Ni catalysts. The catalytic performances of the supported Ni catalysts on different oxides including SiO2, TiO2, ZrO2, γ-Al2O3, and MgO as well as several com. hydrogenation catalysts were investigated. The Ni/ZrO2 catalyst presented the highest 5-AP yield. The characterization results of the oxide-supported Ni catalysts showed that the Ni/ZrO2 catalyst possessed high reducibility and a high surface acid d., which lead to the enhanced activity and selectivity of the catalyst. The effect of reaction parameters on the catalytic performance of the Ni/ZrO2 catalyst was studied, and a high 5-AP yield of 90.8% was achieved in the reductive amination of 2-HTHP aqueous solution under mild conditions of 80°C and 2 MPa H2. The stability of the Ni/ZrO2 catalyst was studied using a continuous flow reactor, and only a slight decrease in the 5-AP yield was observed after a 90-h time-onstream. Addnl., the reaction pathways for the reductive amination of 2-HTHP to synthesize 5-AP were proposed. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Computed Properties of 111-29-5

Bretzler, Patrick; Huber, Michael; Nickl, Simon; Koehler, Klaus published an article in 2020, the title of the article was Hydrogenation of furfural by noble metal-free nickel modified tungsten carbide catalysts.Name: Pentane-1,5-diol And the article contains the following content:

Nickel-tungsten carbide catalysts convert furfural to high value products in a liquid phase catalytic reaction. The product distribution depends on the solvent and the Ni-W-ratio of the catalyst. In iso-Pr alc. a combination of Ni and WxC enables the opening of the furan ring to yield 1,2-pentanediol. Nickel accelerates the tungsten oxide reduction in the tungsten carbide catalyst synthesis and facilitates the carbon insertion. Nickel modified tungsten carbide is a promising, noble metal-free catalyst system for the upgrading of furfural based renewable resources. Its preparation is facilitated compared to unmodified tungsten carbide catalysts. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Name: Pentane-1,5-diol

Matsagar, Babasaheb M.; Hsu, Chang-Yen; Chen, Season S.; Ahamad, Tansir; Alshehri, Saad M.; Tsang, Daniel C. W.; Wu, Kevin C.-W. published an article in 2020, the title of the article was Selective hydrogenation of furfural to tetrahydrofurfuryl alcohol over a Rh-loaded carbon catalyst in aqueous solution under mild conditions.Synthetic Route of 111-29-5 And the article contains the following content:

We describe the selective hydrogenation of furfural (FAL) into tetrahydrofurfuryl alc. (THFA) under mild conditions (30°C) in aqueous media using an Rh-loaded carbon (Rh/C) catalyst in a one-pot fashion. In FAL hydrogenation, the Rh/C catalyst showed a high THFA yield (92%) with 93% selectivity in aqueous media within 12 h, whereas the use of a dimethylacetamide (DMA) solvent system resulted in a 95% THFA yield within 32 h at 30°C. The study of the effect of the solvent on FAL hydrogenation reveals that polar solvents showed higher THFA yields than a toluene solvent. The Rh/C catalyst used in this study exhibited higher activity compared to Ru/C, Pd/C, Ni/C derived from Ni-based metal-organic framework (Ni-MOF), and Ni-loaded carbon black (Ni/CB) catalysts in FAL-to-THFA hydrogenation. The Rh/C catalyst is characterized in detail using various characterization techniques such as TEM, XRD, N2-adsorption-desorption, XPS, and ICP-OES to understand its physicochem. properties. The Rh/C catalyst shows similar high THFA yields in the recycling experiment of FAL hydrogenation under ambient conditions. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Synthetic Route of 111-29-5

On July 21, 2021, Shao, Yuewen; Guo, Mingzhu; Wang, Junzhe; Sun, Kai; Zhang, Lijun; Zhang, Shu; Hu, Guangzhi; Xu, Leilei; Yuan, Xiangzhou; Hu, Xun published an article.Safety of Pentane-1,5-diol The title of the article was Selective Conversion of Furfural into Diols over Co-Based Catalysts: Importance of the Coordination of Hydrogenation Sites and Basic Sites. And the article contained the following:

1,5-Pentanediol (1,5-PDO) is a feedstock for synthesis of polyesters and polyurethanes, and its selective production from furfural is a desirable route but very challenging. In this study, the production of 1,5-PDO from furfural was investigated over the Co-Mg-Al catalyst, containing abundant hydrogenation sites and basic sites. Using layered double hydroxides as the catalyst precursor benefited dispersion of metallic Co particles via preventing migration of cobalt species and developing pore structures. Furthermore, the Co-Mg-Al catalyst possessed abundant basic sites, rendering its superior catalytic activity to Co-Al or Co-Mg catalysts. In situ diffuse reflectance IR spectroscopy (DRIFTS) characterization for FA conversion demonstrated that the cooperation of abundant hydrogenation sites and basic sites facilitated a strong adsorption of C-O-C and carbon-carbon double-bond groups, which benefited the conversion of FA into diols. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Safety of Pentane-1,5-diol

Bains, Amreen K.; Kundu, Abhishek; Maiti, Debabrata; Adhikari, Debashis published an article in 2021, the title of the article was Ligand-redox assisted nickel catalysis toward stereoselective synthesis of (n+1)-membered cycloalkanes from 1,n-diols with methyl ketones.Computed Properties of 111-29-5 And the article contains the following content:

A well-defined, bench-stable nickel catalyst was presented here, that can facilitate double alkylation of a Me ketone to realize a wide variety of cycloalkanes. The performance of the catalyst depends on the ligand redox process comprising an azo-hydrazo couple. The source of the bis electrophile in this double alkylation was a 1,n-diol, so that (n+1)-membered cycloalkanes can be furnished in a stereoselective manner. The reaction followed a cascade of dehydrogenation/hydrogenation reactions and adopted a borrowing hydrogen (BH) method. A thorough mechanistic anal. including the interception of key radical intermediates and DFT calculations supported the ligand radical-mediated dehydrogenation and hydrogenation reactions, which is quite rare in BH chem. In particular, this radical-promoted hydrogenation was distinctly different from conventional hydrogenations involving a metal hydride and complementary to the ubiquitous two-electron driven dehydrogenation/hydrogenation reactions. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Computed Properties of 111-29-5

On February 21, 2020, Jana, Akash; Das, Kuhali; Kundu, Abhishek; Thorve, Pradip Ramdas; Adhikari, Debashis; Maji, Biplab published an article.Electric Literature of 111-29-5 The title of the article was A Phosphine-Free Manganese Catalyst Enables Stereoselective Synthesis of (1 + n)-Membered Cycloalkanes from Methyl Ketones and 1,n-Diols. And the article contained the following:

Herein, we report the stereoselective synthesis of (1 + n)-membered cycloalkane from Me ketone and 1,n-diol. A manganese(I) complex bearing a phosphine-free ligand catalyzed the reaction, which involved the formation of two C-C bonds via a sequence of intermol.- and intramol.-borrowing hydrogenation reactions. It produces 2 mol of water as the sole byproduct, making the process atom economical and environmentally benign. Multisubstituted cycloalkanes were obtained in good to excellent yields with very high selectivities. A thorough mechanistic anal. by high-level DFT computation rationalizes the choice of the pincer and establishes the role of hemilability of the ligand for this efficient transformation.
