The reaction of dipolarophiles with arenealdoxime dehydrodimer

Abstract
The reactions of dipolarophiles with arenealdoxime dehydrodimers 1 have been studied. The reaction products depend upon the dipolarophile used. The reaction of 1 with styrene afford linear adducts. Active dipolarophiles, such as methyl acrylate and dimethyl acetylenedicarboxylate, lead to 1,3‐cycloaddition products. The possible mechanisms for both cases are discussed.
