ChemInform Abstract: A Two-Component Alkyne Metathesis Catalyst System with an Improved Substrate Scope and Functional Group Tolerance: Development and Applications to Natural Product Synthesis.

A catalyst formed in situ upon mixing of a trisamidomolybdenum alkylidyne complex and a trisilanol derivative is highly efficient in metathesis reactions of a series of model compounds comprising primary, secondary or phenolic -OH groups, as well as challenging (bis)propargylic substrates.
