  摘要：

  Onium salts QZ (Z = Cl, Br) having a lipophilic (Q = R3NR', where R' = C16H33) or readily extractable (into organic phase) cation (Q = Ph4P) exhibit a high catalytic activity in phase-transfer alkaline hydrolysis of N-benzyloxycarbonylglycine 4-nitraphenyl ester in the two-phase system chloroform-borate buffer (pH 10). No catalytic effect is observed in the presence of hydrophilic ammonium salts [Et4NCl, Et3PhCH2NCl, Me-2(NH2)NCH2CH2N(NH2)Me(2)(.)2Br(-)] and those insoluble in organic solvents [(Me)(3)NNH(CH2)(2)COO- (.) 2H(2)O, Me-2(NH2)NCH2CO-, Me-2(NH2)N(CH2)(3)SO3-]. These data suggest extraction mechanism of the process. The activity of lipophilic cation Q is determined mainly by two factors: its extractibility, on the one hand, and the ability to form micelles, on the other.
