Through-conjugation of two phosphaalkyne (‘C
P’) moieties mediated by a bimetallic scaffold †
Abstract
Through-conjugation of two phosphaalkyne moieties within an isolable molecule is demonstrated for the first time with the synthesis of [{Ru(dppe)2}2{μ-(CC)2C6H4-p}(C
P)2], via base-induced desilylation of [{Ru(dppe)2}2{μ-(C
C)2C6H4-p}(η1-P
CSiMe3)2]2+. The nature of the cyaphide ligands and their influence upon the bimetallic core are studied electrochemically.
