Abstract

The reactions of [M(≡CC₆H₂Me ₃-2,4,6)X(CO)₂(L)₂] (M = Mo, W; X = Cl, Br; L = pyridine, 3,5-dimethylpyrazole) with Na[H₂B(mt)₂] (mt = methimazolyl) are metal dependent, providing either the alkylidyne complex [Mo(≡CC₆H₂Me₃-2,4, 6)(CO) ₂{κ³-H,S,S′-H₂B(mt)₂}] or the bis(chelate) complex [W(CO){κ²-S,S′-H ₂B(mt)₂}{κ³-H,S,S′-H ₂B(mt)₂}], the latter featuring both bi and tridentate coordination modes for the H₂B(mt)₂ ligand.
