Photolysis of imidazole N(3)-oxides. Formation of unsymmetrical benzil di-imines; X-ray crystal structure of one such di-imine
Abstract
Irradiation of a series of tetra-aryl substituted imidazole N-oxides, in both polar and non-polar media, affords unsymmetrical benzil di-imine derivatives, suggesting that fused oxaziridines are intermediates.
