MOLECULAR-ORGANIZATION OF REAGENTS IN THE KINETICS AND CATALYSIS OF LIQUID-PHASE REACTIONS .5. SOLVENT EFFECTS ON THE KINETIC REGULARITIES OF AMINOLYSIS OF CARBONYL-CONTAINING COMPOUNDS

The kinetic regularities of butylaminolysis of p-nitrophenylmethyl car bonate in solvents of various nature and polarity are studied. The rea ction was found to proceed with the participation of monomeric, dimeri c, and trimeric amine forms; the contributions from diverse routes to the observed rate constant depend on the nature of the solvent It is e stablished that the reaction rate is primarily controlled by the elect ron-donor ability of the solvent involved.
