Abstract

Transformation of the E form of Et cyanoglyoxalate phenylhydrazone (E-I) into Z-I is catalyzed by proton-acceptor-type H-bonding solvents (H-bonding bases). Kinetic and allied data gathered on the approach of E-I towards equil. with Z-I in acetone have been utilized to delimit possible processes by which acetone may catalyze the transformation, under the basic premise that a consequence of H-bonding by the base solvent is enhancement of electron d. at amino N.
