Ring opening reactions of 1-acetyl-4-vinyl-2-azetidinones in the presence of palladium(0)-n-Bu3P catalyst gave 2,4-pentadienamides in good yields, whereas 2-substituted-1,3-dienes were produced by the reaction of 1-sulfonyl-2-vinyl-2-methylazetidines. Ring opening dimerization took place to give 1,7-ditrifluoromethanesulfonyl-1,7-diazacyclododecane in the reaction of 1-trifluoromethanesulfonyl-2-vinylazetidine.
