A compound: 7661-33-8, is researched, SMILESS is O=C1N(C2=CC=C(Cl)C=C2)CCC1, Molecular C10H10ClNOJournal, Organic Chemistry Frontiers called Selective cleavage and reconstruction of C-N/C-C bonds in saturated cyclic amines: tunable synthesis of lactams and functionalized acyclic amines, Author is He, Yan; Yang, Jintao; Zhang, Xinying; Fan, Xuesen, the main research direction is saturated cyclic amine cleavage functionalization tandem reaction; arylpyrrolidinone preparation; tetramethylpiperidinyl arylformamido alkanoate preparation.Formula: C10H10ClNO.

Selective cleavage and functionalization of C-N/C-C bonds in saturated cyclic amines under the promotion of oxoammonium salt and tert-Bu hydroperoxide in the presence of different additives was developed. To be specific, cascade cleavage and reconstruction of C-N and C-C bonds took place under acidic conditions to provide pyrrolidin-2-ones. Under basic conditions, on the other hand, selective cleavage and functionalization of C-C bonds occurred to afford multi-functionalized acyclic N-formal amines. In addition, studies for revealing the intriguing reaction mechanisms was also been performed.

Quality Control of Pyridine-3,5-dicarbonitrile. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Pyridine-3,5-dicarbonitrile, is researched, Molecular C7H3N3, CAS is 1195-58-0, about General and Mild Nickel-Catalyzed Cyanation of Aryl/Heteroaryl Chlorides with Zn(CN)2: Key Roles of DMAP. Author is Zhang, Xingjie; Xia, Aiyou; Chen, Haoyi; Liu, Yuanhong.

A new and general nickel-catalyzed cyanation of hetero(aryl) chlorides using less toxic Zn(CN)2 as the cyanide source has been developed. The reaction relies on the use of inexpensive NiCl2·6H2O/dppf/Zn as the catalytic system and DMAP as the additive, allowing the cyanation to occur under mild reaction conditions (50-80 °C) with wide functional group tolerance. DMAP was found to be crucial for successful transformation, and the reaction likely proceeds via a Ni(0)/Ni(II) catalysis based on mechanistic studies. The method was also successfully extended to aryl bromides and aryl iodides.

SDS of cas: 12080-32-9. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Water’s Role in Polymorphic Platinum(II) Complexes.

Solvent plays a vital role in the recrystallization process and resulting crystallinity of materials. This role is of such importance that it can control the stability and utility of materials. In this work, the inclusion of a solvent in the crystalline lattice, specifically water, drastically affects the overall stability of two platinum polymorphs. [Pt(tpy)Cl]BF4 (tpy = 2,2′;6’2”-terpyridine) crystallizes in three forms, red (1R) and blue (1B) polymorphs and a yellow nonsolvated form (2). 1R is the more stable of the two polymorphs, whereas 1B loses crystallinity upon dehydration at ambient conditions resulting in the formation of 2. Close examination of the solid-state extended structures of the two polymorphs reveals that 1R has a lattice arrangement that is more conducive to stronger intermol. interactions compared to 1B, thereby promoting greater stability. In addition, these two polymorphs exhibit unique vapochromic responses when exposed to various solvents.

Application of 16588-26-4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 3-Bromo-4-chloronitrobenzene, is researched, Molecular C6H3BrClNO2, CAS is 16588-26-4, about Cobalt-Catalyzed C-N Bond-Forming Reaction between Chloronitrobenzenes and Secondary Amines. Author is Toma, Gabriel; Yamaguchi, Ryohei.

Cyclic secondary amines react with mono- or dichloronitrobenzenes in the presence of a catalytic amount of cobalt(II) chloride. Phosphane ligands are beneficial for the reaction, although the bite-angle effect was not strong. The resulting nitro-substituted tertiary amines are important as bioactive compounds and can also be intermediates for the synthesis of substituted anilines. This work represents the first cobalt-catalyzed approach to C-N bond-forming reactions involving aromatic chlorides and cyclic secondary amines. The reaction is ortho- and para-selective, with meta-substituted halides being unreactive in this procedure.
