Reactions with Diazoazoles, VII. 3H-Azolo-1,2,4-triazoles by 1,8- or 1,12-Electrocyclizations of 3H-Pyrazol-3-one- or 3H-Indazol-3-one (Diorganylmethylene)hydrazones, Respectively

3H-Azolo-1,2,4-triazoles 3 are formed by cycloreactions of diazoazoles 1 with diazoalkanes 2 and with fluorene-N-,P-,S-ylides 4, respectively, (Method A) or by cyclizing dehydrogenation of diorganylmethanone (1H-azol-3-yl)hydrazones 7 (Method B).In both m
