THE CYCLOADDITION REACTION OF ISOBENZOFURAN WITH SOME TROPONES

Abstract

Abstract Isobenzofuran, generated by two different methods, was taken to the reaction with tropone, 2-methoxytropone,and 2-chlorotropone. The [6+4]-adducts were obtained from these three tropones examined, but the [2+4]-adducts were obtained from the former two. The structures of the adducts have been deduced on the basis of the spectroscopic methods of analyses.
