Group 6 metal-element multiple bonds are critical in group transfer and metathesis reactivity. In particular, alkylidene derivatives of Mo and W bearing M=C double bonds are well known to catalyze the metathesis of olefins. This presentation will highlight our recent efforts to generate group 6 complexes with oxo (M=O), imido (M=NR), alkylidene (M=CHR) and phosphinidene (M=PR) moieties through novel synthetic approaches, and our examination of the catalytic and fundamental reactivity patterns of these new species.
