Reaction of [W(η 2 -PhC 2 Ph) 3 (NCMe)] with o-diphenylphosphino-styrene and -allylbenzene; evidence for novel carbon–carbon double and triple bond cleavage and alkyne insertion reactions

Reaction of [W(η2-PhC2Ph)3(NCMe)] with o-diphenylphosphino-styrene or -allylbenzene leads to either novel reorganisation reactions involving cleavage of carbon–carbon double and triple bonds, or unusual insertion reactions by PhC2Ph into carbon–hydrogen bonds.
