Addition of alcohols and pyrroles to trans-[RuCl2{(Ph2P)2CCH2}2]. A polypyrrole bearing a covalently bound metal–diphosphine complex†

Abstract

Alcohols and pyrroles undergo base-catalysed addition to trans-[RuCl2{(Ph2P)2CCH2}2] to afford trans-[RuCl2{(Ph2P)2CHCH2Z}2] (Z = –OCH2Ph 2a, –OCH2CH2C4H3S-3 2b, –NC4H4 3a, –NC4H3C6H13-3 3b); complexes 2b and 3b are suitable for electropolymerization to give heterocyclic conducting polymers, and 3b is copolymerized with N-methylpyrrole to afford a polypyrrole incorporating a functionalized metal–diphosphine complex, for the first time.
