Infrared evidence for tricyclic azirines and didehydrobenzazepines in the matrix photolysis of azidonaphthalenes

Abstract

U.v. irradiation of 1- and 2-azidonaphthalene in N₂ or Ar matrices at 12 K leads to the formation of didehydrobenzazepines via photolabile precursors which are assigned tricyclic azirine structures.
