The reaction of diphenyl-, dichloro-, and chloroketenes with several siloxy dienes results in (4 + 2) and/or (2 + 2) cycloaddition products depending primarily on substitution in the diene.The (4 + 2) cycloaddition products are easily hydrolyzed to pyranones.These results are discussed in terms of a dipolar intermediate.
