Alternating Copolymerization

The copolymerization of carbon monoxide with different olefins bearing carbamate and amide functionalities was effected using [Pd(CH3CN)4](BF4)2 as the catalyst and (R,R)-Me-DUPHOS (2:1 (v/v) MeNO2–MeOH or CH2Cl2 as the solvent). The products constitute a new class of functionalized copolymers, and were found to be optically active with a mixture of 1,4-ketone and spiroketal repeating units in the backbone. The influence of different parameters on the copolymerization of methyl N-(3-butenyl)carbamate with carbon monoxide was examined.Key words: copolymerization, carbon monoxide, olefins bearing carbamate and amide functionalities.
