Carroll reaction of 1, 1-diphenyl-2-propynyl acetoacetate results in the formation of 3, 5-hexadien-2-one derivative (IIIc) besides 2, 4-hexadienoic acid derivatives (IV and IV'). IV and IV'are proved to be geometrically isomers by the comparison of their nuclear magnetic resonance data. Other reactions are explained.
