Abstract

Oxidative addition of the sulfur-sulfur bond of 2,2′-pyridine disulfide (C5H4NS-SC5H4N) with L3W(CO)3 [L = pyridine, 1/3 CHPT; CHPT = cycloheptatriene] in methylene chloride solution yields the seven-coordinate W(II) thiolate complex W(η2-mp)2(CO)3 (mp = monoanion of 2-mercaptopyridine). This complex undergoes slow further oxidative addition with additional pyridine disulfide, yielding W(η2-mp)4. Reaction of W(η2-mp)2(CO)3 with NO results in quantitative formation of the six-coordinate W(O) complex W(η2-mp)2(NO)2. Reaction of W(η2-mp)2(CO)3 with NO in the presence of added pyridine disulfide yields the seven-coordinate W(II) nitrosyl complex W(η2-mp)3(NO) as well as W(η2-mp)2(NO)2 and trace amounts of W(η2-mp)4. The complex W(η2-mp)3(NO) is formed during the course of the reaction and not by reaction of W(η2-mp)4 or W(η2-mp)2(NO)2 with NO under these conditions. The crystal structures of W(η2- mp)2(CO)3, W(η2-mp)2(NO)2, and W(η2-mp)3(NO) are reported.
