Sulfur(II)-metal coordination compounds. Group VI metal carbonyl complexes with N,N′-thiobisamines ligands

Abstract

The novel complexes M(CO)5S(NR2)2 (M = Cr, Mo or W) have been prepared by the addition of N,N′-thiobisamine (NR2 = dimethylamine, piperidine, morpholine or dibenzylamine) to UV-irradiated tetrahydrofuran solutions of M(CO)6. The IR, 1HNMR, and UV-visible spectral data used for characterizing the products support the coordination of the thiobisamine via the sulfur(II) atom. © 1984.
