Recent advances in the development of alkyne metathesis catalysts

Abstract

The number of well-defined molybdenum and tungsten alkylidyne complexes that are able to catalyze alkyne metathesis reactions efficiently has been significantly expanded in recent years.The latest developments in this field featuring highly active imidazolin-2-iminato- and silanolate-alkylidyne complexes are outlined in this review. © 2011 Wu and Tamm; licensee Beilstein-Institut.
