Abstract

Synthetic routes are reported to complexes of the form [MI-(alkyne)(CO) {H_nB(mt)_4-n}] (mt = methimazolyl; n = 1, 2; M = Mo, W) through the reactions of alkyne complexes [WI₂(HC≡CSiMe ₃)₂(CO)₂] or [MI₂(RC≡CR) ₂(NCMe)(CO)] (M = Mo, W; R = Me, Ph) with the salts Na[H _nB(mt)_4-n]. The derivative [MoI(PhC≡CPh)(CO)(HB(mt) ₃)] reacts with Na[HB(mt)₃] to provide the complex [Mo(PhC≡CPh)-(CO){HB(mt)₃}₂] in which the two HB(mt)₃ ligands adopt different non-interconverting coordination modes, κ³-S,S′,S″ and κ¹-S.
