摘要

Summary Irradiation of 3-(N-methylanilino)-2 H-azirines with a mercury low pressure lamp induces the cleavage of the C (2), C (3)-ring bond thus affording nitriliomethanide dipols, substituted by an amino group at C (1). Depending on the substitution pattern at C (3), these intermediates can be trapped by dipolarophiles to yield five-membered heterocycles with high regioselectivity, or they undergo a 1, 4-H-shift forming 2-azabutadiene derivatives. ...
