The rates of the acid-catalyzed hydrolysis of methyl dimethyl-, diethyl-, diisopropyl-, and di- tert-butylphosphinate in D2SO4-D2O and of p-methoxybenzyl, p-chlaorobenzyl, p- nitrobenzyl, and benzyl diethylphosphinate in H2SO4-70% w/w DMSO-H2O have been studied. The bell-shaped p H-rate profiles, the Bunnett-Olsen Φ (0.91 to 1.28), Bunnett w (2.28 to 3.52) and w*(-0.94 to+ 0.17), and Yates-McClelland r (0.61 to 2.6) values, and the ...
