Synthesis of group 6 metal carbonyl complexes containing oxygen- and sulfur-functionalized 1,2,4-triazoles
文摘
Reaction of RCOCH2Tz and PhCOCH(CH2SPh)Tz with M(CO)6 or M(CO)5THF results in RCOCH2TzM(CO)5 and PhCOCH(CH2SPh)TzM(CO)5 (R = phenyl or ferrocenyl, Tz = 1,2,4-triazol-1-yl and M = Mo or W). X-ray crystal structure analyses show that the triazolyl group acts as a monodentate ligand through the exodentate nitrogen atom in these complexes. The electrochemical behavior of these complexes has been investigated by cyclic voltammetry.
