Towards Highly Active and Robust Alkyne Metathesis Catalysts: Recent Developments in Catalyst Design

摘要

Though alkyne metathesis has crossed several barriers after the initial discovery of the heterogeneous catalyst system based on tungsten oxide and silica, it is still in its infancy as a synthetic method. It is highly desired to develop a catalyst that can operate under ambient conditions and tolerate air and moisture without compromising the metathesis activity and functional-group compatibility. This Highlight is intended to showcase some recent developments in the catalyst design and spotlight the immense potential of this unique multi-bond-exchange reaction.
