Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Katlenok, Eugene A., once mentioned the application of 6674-22-2, Name is 2,3,4,6,7,8,9,10-Octahydropyrimido[1,2-a]azepine, molecular formula is C9H16N2, molecular weight is 152.2367, MDL number is MFCD00006930, category is benzoxazole. Now introduce a scientific discovery about this category, Recommanded Product: 6674-22-2.
Supramolecular Assembly of Metal Complexes by (Aryl)I…dz2 [Pt-II] Halogen Bonds
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.
