Synthesis and UV spectra of 8-mercaptoquinoline organosilicon derivatives and their metal halides complexes
摘要:
IR and UV spectra of (8-quinolylthiomethyl)trimethylsilane (1), -trimethoxysilane (2), -silatrane (3) and their complexes with CuCl2, ZnCl2, PtCl2 and SnCl4 in MeCN have been studied. The UV spectra of 8-methylthioquinoline, its HN+ cation and HN+, HS+ dication were calculated at the AM1 (Cl) level. It was shown that 1(.)PtCl(2), 2(.)ZnCl(2) and 3(.)ZnCl(2) are chelates. The 2(.)SnCl(4) and 3(.)SnCl(4) compounds have a strong N --> Sn bond. The 2(.)CuCl(2) and 3(.)CuCl(2) complexes are a mixture of coordination compounds having N --> Cu or N --> Cu <-- S bonds.
