Addition of alcohols and pyrroles to trans-[RuCl₂{(Ph₂P)₂C[double bond, length half m-dash]CH₂}₂]. A polypyrrole bearing a covalently bound metal–diphosphine complex†

Abstract

Alcohols and pyrroles undergo base-catalysed addition to trans-[RuCl₂{(Ph₂P)₂C[double bond, length half m-dash]CH₂}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.
