Synthesis and α-substitution reactions of methoxime derivatives of alkene-carbon monoxide alternating copolymers

Abstract

Poly(1-methoxyiminotrimethylene) 5 and poly[(1-meth-oxyiminotrimethylene)-co-(1-methoxyimino-3-methyltrimethylene)] 6, prepared by reaction of ethene/propene–carbon monoxide alternating copolymers with methoxylamine, undergo α-substitution on treatment with BuLi followed by addition of electrophiles such as MeI.
