Tetrazanes as intermediates in the oxidation of N-amino-lactams
Abstract
Tetrazanes (3) are obtained by the oxidation of N-aminophthalimide (1), 1-amino-2-quinolone (4), and 1-amino-3-isopropenylbenzimidazolin-2-one (5), with iodosobenzene diacetate; they give the parent lactams on mild heating, and the trans-tetrazenes on further oxidation.
