Phenylnitrene azobenzene formation

The formation of phenylnitrene by thermolysis of 0,Af-bis(trimethylsilyl)-JV-phenylhydroxylamine at 100°C has an activation enthalpy of 27.7 kcal/mol and is supported by the formation of aniline, azobenzene, or an 85-95% yield of 2-diethylamino-3f/-azepine in the presence of diethylamine (Eq. 65).262... [Pg.300]

The high dilution of solutions of phenyl azide suppresses polymer formation and azobenzene forms instead. This indicates that singlet intermediates (50 and/or 51) serve as a reservoir for triplet phenylnitrenes ( 52), which either undergo dimerization or react... [Pg.327]
