摘要

The reaction of 1-(disubstituted amino)-2, 3-diphenylcyclopropenium salt with phenyl-and alkylmagnesium halides afforded, regioselectively, 1-aminocyclopropenes in good yields. The reactions of these 1-aminocyclopropenes were studied under acidic and nonacidic conditions to yield regioselective ring-opening products (C 2–C 3 and C 1–C 3 bond fissions of the cyclopropene) associated with the carbenium ions and carbene intermediates, ...
