Abstract

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 of nitriles with alkynes, in which the organic CR fragments of two nitriles are coupled to yield an alkyne. A simple "sacrificial" alkyne (3-hexyne) acts as the N-atom acceptor, forming two equivalents of nitrile byproduct (propionitrile).
