Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Photochemistry of 1,5-Cyclooctadiene Platinum Complexes for Photoassisted Chemical Vapor Deposition.Application of 12080-32-9.

Quantum yields for disappearance of (COD)PtMe2 (1a) and (COD)PtMeCl (1b) were determined at 334 nm in C6D6 solvent. Chain reactions initiated by formation of a Me radical were proposed to be the cause of quantum yields higher than unity (Φ = 5.52 ± 0.40 for 1a) when the reaction mixtures included C4F9I. The chain reactions were suppressed in the presence of the radical trap 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO), which resulted in measured disappearance quantum yields of Φ = 0.037 ± 0.003 for (COD)PtMe2 and Φ = 0.44 ± 0.02 for (COD)PtMeCl at 334 nm. Weak luminescence was observed for 1a and 1b, and it was determined that emissive decay is not competitive with Pt-CH3 bond homolysis. DFT studies enabled assignment of both SBLCT and MLCT transitions in the UV/vis spectra of 1a, while 1b only exhibits MLCT transitions. These effects can be attributed to the symmetry of the mol. and its electronic structure.

The Pt-catalyzed addition of silanes to functional groups such as alkenes, alkynes, carbonyls and alcs., i.e. the hydrosilylation reaction, is a fundamental transformation in industrial and academic chem., often claimed as the most important application of Pt catalysts in solution However, the exact nature of the Pt active species and its mechanism of action is not well understood yet, particularly regarding regioselectivity. Here, exptl. and computational studies together with an ad hoc graphical method show that the hydroaddn. of alkynes proceeds through Pt-Si-H clusters of 3-5 atoms (metal(oid) association) in ppm amounts (ppm), which decrease the energy of the transition state and direct the regioselectivity of the reaction. Based on these findings, new extremely-active (ppm) microporous solid catalysts for the hydrosilylation of alkynes, alkenes and alcs. have been developed, paving the way for more environmentally-benign industrial applications.

This paper presents adsorption isotherm data of CO2 on four different metal oxides. Absolute adsorption isotherms of CO2 at 313 K on WO3 and at T = 313 K, 333 K, 353 K on CeO2, TiO2 and Al2O3 and pressures up to p = 25 MPa were determined from CO2 excess adsorption isotherms. It was found at 313 K a maximum absolute loading of 0.3 mmol g-1 for WO3, of 1.7 mmol g-1 for CeO2, of 3.1 mmol g-1 for TiO2 and of 6.3 mmol g-1 for Al2O3. All adsorption isotherms were fitted to the Freundlich, Langmuir, Pade, Sips and Toth models and the Pade model present a better fitting than the other models. Based on these data, the Pade and the Langmuir model were used to determine the isosteric enthalpy of adsorption which was found to be dependent on the loading and the used model.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 12080-32-9, is researched, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2PtJournal, Journal of Molecular Structure called Spectroscopic, structural and DFT studies of luminescent Pt(II) and Ag(I) complexes with an asymmetric 2,2′-bipyridine chelating ligand, Author is Yilmaz, Ismail; Acar-Selcuki, Nursel; Coles, Simon J.; Pekdemir, Fatih; Sengul, Abdurrahman, the main research direction is carbomethoxybipyridine preparation platinum silver complexation; crystal mol structure methylcarbomethoxybipyridine platinum silver complex; DFT luminescent platinum silver methylcarbomethoxybipyridine asym bipyridine chelating ligand.Recommanded Product: 12080-32-9.

A new unsym. substituted 2,2′-bipyridine ligand, 5-methyl-5′-carbomethoxy-2,2′-bipyridine (L) was isolated from the dry distillation of the copper(II) complex, mono-aqua-bis(trans-5-methyl-pyridine-2-carboxylato-N,O)copper(II). The ligand was fully characterized. The spectroscopic and single-crystal x-ray diffraction (SCXRD) studies of the coordination compounds of the ligand with platinum(II) and silver(I); cis-Pt(L)Cl2 (1) and [Ag(L)2]PF6 (2), resp. are reported. In 1, the Pt center coordinates to tertiary N atoms of the ligand and two chloride ions to form a neutral square-planar coordination sphere, while in 2, the Ag(I) center is coordinated by two ligands through N atoms to generate a cationic flattened tetrahedron geometry in which two mean planes intersect each other at 50.93°. The pyridine rings are nearly coplanar as revealed by the torsion angle of N2-C7-C6-N1 1.32(5)°. In both complexes, L acts as a chelating ligand through pyridyl N atoms. In 1, the mol. units are stacked in a head-to-tail fashion with a Pt···Pt separation of 3.5 Å. Supramol. self-assembly of the mol. units by extensive intermol. contacts through C-H···Cl and C-H···O between the adjacent units results in an infinite two-dimensional flattened-out herringbone structure in the crystalline state. In 2, the mol. units are interconnected with each other by C-H···O contacts between the adjacent units running parallel to each other. Both complexes are fluorescent in solution and have emission maxima in the UV-Vis regions, which is a very important property for optoelectronic applications. DFT (d. functional theory) and TD-DFT (time-dependent-DFT) calculations were performed at B3LYP/6-311+G(d,p)/LANL2DZ level to explore structural, electronic, and spectroscopic properties to compare with the exptl. results. The MOs were carried out with DFT at the same level.

New downstream synthetic route of 12080-32-9

There is still a lot of research devoted to this compound(SMILES：C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-])Quality Control of Dichloro(1,5-cyclooctadiene)platinum(II), and with the development of science, more effects of this compound(12080-32-9) can be discovered.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about The importance of intramolecular conductivity in three dimensional molecular solids, the main research direction is macrocyclic semiconductor preparation crystal structure electron mobility conductivity.Quality Control of Dichloro(1,5-cyclooctadiene)platinum(II).

Recent years have seen tremendous progress towards understanding the relation between the mol. structure and function of organic field effect transistors. The metrics for organic field effect transistors, which are characterized by mobility and the on/off ratio, are known to be enhanced when the intermol. interaction is strong and the intramol. reorganization energy is low. While these requirements are adequate when describing organic field effect transistors with simple and planar aromatic mol. components, they are insufficient for complex building blocks, which have the potential to localize a carrier on the mol. Here, we show that intramol. conductivity can play a role in controlling device characteristics of organic field effect transistors made with macrocycle building blocks. We use two isomeric macrocyclic semiconductors that consist of perylene diimides linked with bithiophenes and find that the trans-linked macrocycle has a higher mobility than the cis-based device. Through a combination of single mol. junction conductance measurements of the components of the macrocycles, control experiments with acyclic counterparts to the macrocycles, and analyses of each of the materials using spectroscopy, electrochem., and d. functional theory, we attribute the difference in electron mobility of the OFETs created with the two isomers to the difference in intramol. conductivity of the two macrocycles.

Category: alcohols-buliding-blocks. 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 Synthesis and structure of thienyl Fischer carbene complexes of PtII for application in alkyne hydrosilylation.

Transmetalation of Group 6 thienylene Fischer carbene complexes to Pt(II) precursors yielded new examples of neutral Pt(II) bisethoxycarbene complexes with either 2-thienyl (T) or 5-thieno[2,3-b]thienylene (TT) carbene substituents. The use of analogous aminocarbene group 6 precursors proceeded to give isomeric Pt(II) product mixtures where the resultant bisaminocarbene ligands displayed different orientations due to restricted rotation around the Pt-aminocarbene bond caused by the sterically demanding TT substituents. The well-defined Pt(II) ethoxycarbene complexes were screened as catalyst precursors in the benchmark hydrosilylation reaction employing phenylacetylene and triethylsilane substrates. Marked selectivity for the β-E isomer (E)-triethyl(styryl)silane was observed, and the (pre)catalysts proved recyclable, active in solvent-free reactions, and displaying a high alkyne functional group tolerance.
