The tungsten benzylidyne complex [PhC≡W{OSi(OtBu)3} 3] efficiently catalyzes the metathesis of conjugated diynes and ring-closing diyne metathesis (see scheme). Although this reaction implies C-C single-bond activation, 13C labeling studies reveal that it proceeds by classical alkylidyne group exchange and involves cleavage and formation of carbon-carbon triple bonds.
