Photochromic spin traps. Part 3.1,2 A new phosphorylated spiro[indoline-naphthoxazine]†
Abstract
The synthesis and characterisation of a new phosphorylated nitrone belonging to the spiro[indoline-naphthoxazinic] family are described. The results of spin trapping experiments which indicate the ability of this photochromic nitrone to react with carbon-, oxygen- and sulfur-centred radicals are also reported.
