Chemistry of Nitrenes Generated by the Photocleavage of Both Azides and a Five-Membered Heterocycle

Article abstract of DOI:10.1021/ja00018a032

Pyrazolo<1,2-a>benzotriazole and some of its derivatives (2a-c) are photochemically cleaved to form 2-(1-pyrazolyl)phenylnitrenes, which are also obtained through a more conventional path by photodecomposition of the pyrazolylphenyl azides (1a-c).Product
