N2 - Reaction of alkylidyne complexes [M(CCH2But)-{P(OMe) 3}2(η-C5H5)] (M = Mo, W) with 2,6-xylyl isocyanide affords first [M(CCH2But) (CN-2,6-Me2C6H3)-{P(OMe)3}(η- C5H5)] then [M{η3-RN=C ⋯ C(CH 2But) ⋯ C=NR}(CNR)2(η-C 5H5)] (R = 2,6-Me2C6H3), the molybdenum complex being identified by X-ray crystallography; in contrast, CO displaces the phosphite ligands to give sequentially [Mo (CCH 2But)(CO) {P(OMe)3 }-(η-C5H 5)] and [Mo(CCH2But)(CO)2(η- C5H5)].
