Reactions of Transition Metal σ-Acetylide Complexes. XIII. Alkylation and Related Reactions

Abstract

A series of 20 cationic vinylidene complexes of ruthenium and osmium [M(CCRR′)(L)(L′)(η- C5H5)]+ (R′ = Me, Ph, C6H4F-4, C6F5, (CH2)2C2H; R′ = Me, CH2Ph, CH2CH=CH2, CH2C2CH, (CH2hBr; L, L′=PPh3, CNBUT, dppm, dppe; not all combinations), [{Ru (CCRCH2-)(PPH3)2( η- C5H5)2]2+ and [CH2{ CPhCRu (PPh3)2(η-C5H5)]2]2+ have been obtained from reactions between the metal acetylide complexes and the appropriate organic halides.
