Alkyne metathesis by molybdenum and tungsten alkylidyne complexes

摘要

Alkyne metathesis by molybdenum and tungsten alkylidyne complexes is now ～45 years old. Progress in the practical aspects of alkyne metathesis reactions with well-defined complexes, as well as applications, in the last decade, guarantees that it is destined to become a useful method for the synthesis of organic molecules.
