Kinetic measurements and product identifications have been carried out in order to elucidate the mechanisms of several more imine ring openings. Aziridines studied were 2,2-dimethylethylenimine, 2-ethylethvlenimine, N-(ra-butyl)-ethvlenimine and ethylenimine; nucleophiles studied were acetate, bromide, chloride, iodide, thiocyanate and thiosulfate ions, thiourea and water. Hydrolysis rates were studied over a range of temperature and pressure so as to obtain activation parameters.All of the reactions studied have been found to correlate with known mechanistic patterns. The use of linear free energy equations for the evaluation of relative contributions of Sxl and Sn2 behavior in solvolysis reactions is pointed out.
