摘要

The first catalytic cross-metathesis reaction of an alkyne with a nitrile is described. The nitride complex N⋮ W (OC (CF3) 2CH3) 3 (DME) undergoes reversible triple-bond metathesis reactions with alkynes (RC⋮ CR; R= Et, 4-C6H4OMe), forming the alkylidyne complexes RC⋮ W (OC (CF3) 2CH3) 3 (DME)(R= Et, 4-C6H4OMe) along with the corresponding nitrile RC⋮ N. This has been exploited to effect catalytic cross-metathesis ...
