SUBSTITUENT EFFECTS IN THE RING-CHAIN TAUTOMERISM OF 1,2-DIARYLIMIDAZOLIDINES
1,2-Diaryl-substituted imidazolidines proved to be ring-chain tautomeric mixtures in CDCl3 at 300 K. Both 1- and 2-aryl groups exerted significant electronic effect on the tautomeric equilibria, which could be described by the equation log KX=ρ
