摘要

Triplet-sensitized irradiation of 2-aza-1, 4-dienes affords N-cyclopropylimines via 2-aza-di-π- methane (2-ADPM) rearrangement pathways. In the case of the pentaphenyl-substituted azadiene 1, irradiation leads to formation of cyclopropylimine 2 as well as N-vinylaziridine 3. The transformations represent the first examples of di-π-methane rearrangement reactions that yield three-membered heterocyclic products. SET-sensitized irradiation of 2-aza-1, 4- ...
