New Advances in Chemical Research in 2021. Catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 6674-22-2, Name is 2,3,4,6,7,8,9,10-Octahydropyrimido[1,2-a]azepine, molecular formula is , belongs to benzoxazole compound. In a document, author is Katlenok, Eugene A., Product Details of 6674-22-2.
The theoretical data for the half-lantern complexes [{Pt(CN<^>)(mu-SN<^>)}(2)] [1-3; CN<^> is cyclometalated 2-Ph-enzothiazole; SN<^> is 2-SH-pyridine (1), 2-SH-benzoxazole (2), 2-SH-tetrafluorobenzothiazole (3)] indicate that the Pt…Pt orbital interaction increases the nucleophilicity of the outer dz2 orbitals to provide assembly with electrophilic species. Complexes 1-3 were co-crystallized with bifunctional halogen bonding (XB) donors to give adducts (1-3)(2).(1,4-diiodotetrafluorobenzene) and infinite polymeric [1.1,1 ‘-diiodoperfluorodiphenyl](n). X-ray crystallography revealed that the supramolecular assembly is achieved through (Aryl)I…dz2[Pt-II] XBs between iodine sigma-holes and lone pairs of the positively charged (Pt-II)(2) centers acting as nucleophilic sites. The polymer includes a curved linear chain…Pt-2…I(arene(F))I…Pt-2… involving XB between iodine atoms of the perfluoroarene linkers and (Pt-II)(2) moieties. The Pt-195 NMR, UV/Vis, and CV studies indicate that XB is preserved in CH(D)(2)Cl-2 solutions.
