The number of well-defined molybdenum and tungsten alkylidyne complexes
capable of efficiently catalyzing the reversible making and breaking of carbon-carbon
triple bonds has increased significantly in recent years, allowing alkyne metathesis to
be used as a powerfool tool in organic synthesis, supramolecular chemistry, and
material science.[1-3] Some of the latest developments in this field are presented,
with emphasis on the author’s contributions to the field, which include highly active
imidazolin-2-iminato- (1), phosphoraneiminato- (2), and silanolate-alkylidyne
complexes (3), as well as alkylidyne complexes such as 4, solely supported by
fluoroalkoxide ligands.
