Reaction Steps

Dimethyl acetylenedicarboxylate (6.3 g) and chloroprene (6.2 g) were heated at 50° C. for 25 hours. The reaction mixture was distilled under reduced pressure and the fraction boiling at 135° to 138° C. at 2.5 torr was collected. The thick oil weighed 4.6 g (100% yield based on unreacted dimethyl acetylenedicarboxylate).
