The scope of enamine formation by a procedure where the carbonyl compound is added to a preformed titanium tetrachloride-amine complex was investigated with a series of different types of carbonyl compounds and two secondary amines (morpholine and pyrrolidine).The carbonyl compounds include aldehydes, cyclic ketones and some substituted aryl alkyl ketones.Yields of isolated products were in the range 67-100 percent with the exception of the pyrrolidine enamine from camphor which gave 53 percent of the isolated product.

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.
