| 内容記述 | The second-order rate constants for the base-catalysed reactions of methanol with 3-methoxy- and 3-methylthio-acrylophenones (MeOAcr and MeSAcr) have been determined in methanol and in methanol-OD at 25℃. Non-catalytic terms were not detected. Inverse kinetic solvent isotope effects on attack of methoxide ion on MeOAcr and MeSAcr of 0.62 and 0.57, respectively, are compared with earlier data for attack of methoxide ion on a substituted N -benzylideneaniline. The rate constants depend on electrophiles, but the solvent isotope effects, ca. 0.6, are fairly constant, irrespective of the 10⁴ fold variance of the rate constants. The results are discussed in terms of solvent reorganisation. The solvent isotope effect for the reaction of hydroxide ion in water was also determined. | |||||||
