TAUTOMERISM AND STEREODYNAMICS OF INDOPHENOLS AND AMIDINES AND THEIR DERIVATIVES AND ANALOGS. I. EFFECT OF INTRAMOLECULAR HYDROGEN BONDING ON THE KINETICS AND MECHANISM OF ZE ISOMERISATION OF ortho-INDOPHENOLS

1.The actual mechanism for the ZE isomerization of ortho-indophenols involves planar inversion of configuration at the C=N bond.The rates of this process range from 1E-6 to 1E-7 sec-1 and increase to 1E11 sec-1 upon the conversion of the ortho-indophenols to paramagnetic forms (at 298 K). 2.The existence of intramolecular hydrogen bonding in ortho-indophenols leads to hydrogen bond dissociation and formation and torsional twisting of the phenol fragment concerted with planar inversion at the C=N bond. 3.The stereodynamics of para-indophenols is a function of intermolecular proton exchange.ZE isomerization by a torsional twisting mechanism is possible only by blocking the p-electron pair of the imine nitrogen by N-methylation.
