Hydrogenating an organometallic carbon chain: buten-yn-diyl (CH = 001;CHC C) as a missing link
The sequential reaction of [Ru(CuCCuCH)Cl(CO)2(PPh3)2] with [Ru(CO)2(PPh3)3], and N-chlorosuccinimide affords the binuclear tetracarbido complex [Ru2(μ-CuCCuC)Cl2(CO)4(PPh3)4]. This may be compared with the first example of a butenyndiyl bridged bimetallic complex [Ru2(μ-CHvCHCuC)Cl2(CO)4(PPh3)4] which is obtained from the reaction of [Ru(CuCCuCH)Cl(CO)2(PPh3)2] with [RuHCl(CO)(PPh3)3] followed by carbonylation. Characterisational data are discussed with reference to constituent model...[Show more]
