Reactions with Diazoazoles, VIII. - Syntheses of Azolo-1,2,3,5-tetrazin-4(3H)-ones

Azolo-1,2,3,5-tetrazin-4(3H)-ones 4 and 5 are formed by cycloaddition reactions of α-diazoazoles 2 with aryl or alkyl isocyanates 3a-p, respectively, as well as with diisocyanates 3q,r (Method A).Alternative syntheses for 4 are presented by diazoti
