Hydrazines iminophosphoranes

The iminophosphorane (352) reacts with acyl chlorides to give the corresponding 3-substituted 1,7-dimethyl-l,4-dihydro-6//-[l,2,4]triazino[4,3-6][l,2,4,5]tetrazin-6-ones (353). The same compounds were obtained by reaction of the amino-hydrazine (354) with aldehydes and dehydrogenation of the... [Pg.555]

Benzeneseleninic anhydride oxidizes hydrazines to azo-compounds and hydrazones to acylazo-compounds. Azo-compounds have also been synthesized by photolysis of iminophosphoranes, reaction of hydrazones with allyl acetate under nickel catalysis/ reaction of A/-methyl-N-tosylhydrazones with amines/ and deoxygenation of azoxy-compounds/ ... [Pg.178]
