The effect of the counterion of the "leaving" group in the alkylating agent on the direction of alkylation in the alkali-metal salts of 5-benzylidenerhodanine in the solid phase was investigated.It was shown that the ratio of the isomeric products from alkylation at the N and S atoms varies with variation of the counterion and the substituted group in accordance with the principle of hard and soft acids and bases and increases in the series Li, Na, K, Cs.
REACTIVITY AND TAUTOMERISM OF AZOLIDINES. XXXII. THE EFFECT OF THE NATURE OF THE SOLVENT ON THE DUAL REACTIVITY OF 5-BENZYLIDENERHODANINE IN METHYLATION
Volkova, A. A.,V'yunov, K. A.,Ginak, A. I.,Ramsh, S. M.,Sochilin, E. G.
, p. 117 - 119 (2007/10/02)
The effect of the nature of the solvent on the dual reactivity of 5-benzylidenerhodanine in methylation was investigated.A correlation was obtained between the ratio of the rate constants for the reaction at the N and S centers of the substrate and the polarity of the solvent.Proposals are made concerning the mechanism of solvation of the ambident centers in 5-benzylidenerhodanine.
