In the oxidation of the amino styrenes 1a - 1j only products of the oxidative attack at the C=C double bond and hydrolysis products are obtained.Aprotic dipolar solvents and the addition of molecular sieve 5A promote the oxygen uptake.The addition of hydroquinone to the oxidation system does not influence the rate of oxygen absorption or the yields of the oxidation products.

A process for the preparation of carboxylic acids represented by a formula STR1 wherein R1 represents hydrogen atom or a lower alkyl radical, R2 represents hydrogen atom, lower alkyl or allyl radical and R3 represents phenyl, substituted phenyl, substituted naphthyl, dibenzofuranyl or substituted biphenyl. Following novel enamine and amidine compounds as intermediates for manufacturing the carboxylic acids and processes for the manufacture of said enamine and amidine compounds STR2 wherein R1, R2 and R3 represent the meanings as referred to and R4 represents dimethylamino, pyrrolidyl, piperidyl or morpholyl.
