Description

General description

Dimethyl itaconate undergoes enantioselective Rh(I)-catalyzed hydrogenation which can be enhanced by appropriate choice of substituents on aromatic ring of (1,2-diarylphosphinoxy)cyclohexane.

Application

Dimethyl itaconate may be used in functionalization of isotactic poly(propylene). It was used in crosslinking of polyesters: poly(isosorbide itaconate)and poly(isosorbide itaconate-co-succinate).
