摘要：

Stabilization by coordination: A long sought after intermediate is stabilized by complexation: B(C6F5)3 reacts at a bis(trimethylsilyl) acetylene titanium complex with C-Si bond cleavage and B-C bond formation to give the coordinatively stabilized (trimethylsilyl)alkynylboranate 1. The reaction of the corresponding zirconium complex proceeds totally different giving the agostic complex 2.
