Reactions of bis(tricarbido)mercurials and dimetallaoctatetraynes with [Ru(CO) 2 (PPh 3 ) 3 ]: scission of a C sp -C sp single bond

Abstract

The reactions of [L(CO)2WC6W(CO)2L] (L = HB(pz)3, HB(pz′)3; pz = pyrazol-1-yl, pz′ = dimethylpyrazol-1-yl) with [Ru(CO)2(PPh3)3] provide the bis-(tricarbido) complexes [(Ph3P)2(CO) 2Ru{C3W(CO)2L}2] via the adduct[(Ph3P)2(CO)2Ru{η2-L(CO) 2WC6W(CO)2L}]
