Hydrolysis of Aryl Derivates of Malonaldehyde Dianil. III

The reaction sequence of hydrolysis of N-acyl derivates of malonaldehyde dianil was examined.Hydrichloric acid-catalysed hydrolysis occured at the imino group to form arylamine and β-(N-acylarylamino)acrolein; the latter compound is not stable in acid solution.In the case of 1-(N-phenylcarbamoyl-p-methylphenylamino)-3-(p-methylphenylimino)-1-propene, hydrolysis occured at both the imino and the carbamoyl groups.Buffer catalysed hydrolysis occured at the imino group, and the resulting β-(N-acylarylamino)acrolein and arylamine reacted to form β-arylaminoacrolein and N-arylamine.The aminolysis reaction was suppressed in hydrochloric acid-catalysed hydrolysis.Alkaline hydrolysis of N-acyl derivates of malonaldehyde dianil and of β-arylaminoacrolein occured at the amide carbonyl group except in the case of 1-(N-tosyl-p-methylphenylamino)-3-(p-methylphenylimino)-1-propene.N-tosyl-p-toluidine was obtained in this case.Keywords--hydrolysis; malonaldehyde dianil; β-arylaminoacrolein; 1-(N-acylarylamino)-3-arylamino-1-propene; β-(N-acylarylamino)acrolein; 1-(N-tosyl-p-methylphenyilamino)-3-(p-methylphenylimino)-1-propene; 1-(N-tosyl-p-methylphenylamino)-3-(p-methylphenyilimino-1-butene; β-(N-tosyl-p-toluidino)acrolein; 4-(N-tosyl-p-toluidino)-3-buten-2-one
