Abstract
Enantioselective alternating copolymerization of carbon monoxide with omega -undecylenic acid (Ua), ethyl acrylate (Ea), and butyl acrylate (Ba) were carried out for the first time using palladium catalyst modified by 1,4:3,6 -dianhydro-2,5-dideoxy-2,5-bis(diphenylphosphino)-L-iditol (DDPPI). Optical rotation, elemental analysis, spectra of H-1-NMR, C-13-NMR, and IR showed that our copolymers were optically active, isotactic, alternating poly( 1,4 -ketone) or poly(spiroketal) structure.
