Abstract
|
|
|
|
The effect of substituent in leaving group on the rates of reactions of phenacyl substituted-benzenesulfonates with pyridine was determined conductometrically in acetonitrile and in methanol at 35, 45, and 55℃, respectively. The reaction rate became faster in proportion to electron-attracting ability of substituent, which indicates that the substituent in leaving group can directly control reaction rate. It was shown that the specific to the carbonyl carbon as the rate-determining step.
