It was shown that the reaction of 2-chloro-3-(4-N,N-dimethylaminoanilino)-1,4-naphthoquinone wwith piperidine in the absence of a solvent gives not only a product of replacement of the chlorine atom by a piperidino group, 3-(4-N,N-dimethylaminoanilino)-2-piperidino-1,4-naphthoquinone, but also 2-(4-N,N-dimethylaminoanilino)-1,4-naphthoquinone and 2-(4-N,N-dimethylaminoanilino-2-piperidino)-1,4-naphthoquinone.The latter compounds are the only reaction products formed in dimethyl sulfoxide.The reaction with morpholine occurs in a similar way, whereas that with pyrrolidine gives only a product of replacement of the chlorine atom by hydrogen. - Key words: 2-chloro-(4-N,N-dimethylaminoanilino)-1,4-naphthoquinone, cyclic amines.

The structure of the dinitrone formed on reaction of nitrosobenzene with 1,4-benzoquinone has been confirmed by spectroscopic measurements.An electron transfer radical-anion mechanism is suggested to account for its formation. - Keywords: Addition, Nitrosobenzene, 4-Benzoquinone, Nitroxide, Trap
