Catalytic Nitrile-Alkyne Cross-Metathesis

, 2016
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 ...
