1. The ratio of the rate constants of the interaction of triethyl phosphite with isopropyl iodide and the simultaneous parallel-successive isomerization of triethyl phosphite was determined. At 100° in toluene solution and a pressure of 4000 kg/cm2, the rate constant of the first sterically hindered reaction is approximately 60 times lower than the rate constant of the second reaction. 2. The interaction of triethyl phosphite with tert-butyl chloride at the temperatures 100-200° and pressures up to 12,000 kg/cm2 does not lead to the formation of the diethyl ester of tert-butylphosphinic acid. Diethyl esters of phosphorous and ethylphosphinic acids, ethyl chloride, isobutylene, its dimers and trimers, and higher molecular products of secondary reactions were found in the reaction products. © 1967 Consultants Bureau.
