18.63 18.32 17.3 16.82 16.1 15.73 31.55 31.12 of the type V formed by the condensation of the diaminoquinone with two molecules of the aldehyde. The intermediate products may be oxidized either by atmospheric oxygen or by excess quinone with concomitant cyclization giving the benzdioxazoles (cf. Scheme A). In support of this view is the fact that N-substituted diaminoquinones, for example 2, 5-bis-(benzylamino)-1, 4-benzoquinone (111, R= C7H7) ...
