The N?O bond cleavage of 2-oxa-3-azabicyclo substrates, which are readily prepared by the hetero Diels-Alder reaction between nitroso dienophiles and cyclic 1,3-dienes, was effectively catalyzed by heterogeneous copper-on-carbon (Cu/C) under aqueous condi

Bromine enters the position ortho to nitrogen on nucleophilic addition of hydrogen bromide to N-phenyl-1,4-benzoquinone monoimine.Bromination of the aryl nucleus is a parallel process, which may be suppressed by adding resorcinol to the reaction mixture.Bromine enters the position ortho to oxygen in the reaction of HBr and N-(2,4-dinitrophenyl)-1,4-benzoquinone monoimine.A dependence of the reactivity on the redox potential of the quinone imine was noted.

The oxidation of aromatic primary amines with chromyl chloride in carbon tetrachloride or chloroform, results in the formation of intermediate solid adducts (Etard adducts) which, on hydrolysis, give azobenzenes(1), 1,4-benzoquinones(2), anilino-1,4-benzoquinones(3), 1,4-benzoquinone anils(4) and anilino-1,4-benzoquinone anils(5) in yields which depend on the position, nature and degree of substitution of the ring.
