Abstract
We began our study by examining the reaction of benzyl chloride (1a) with p-toluenesulfinic acid sodium salt (2a) in dioxane by using Pd(OAc) 2 /PPh 3 as catalyst and Na 2 CO 3 as base. When benzyl chloride reacted with an equal amount of 2a under air, the desired product was obtained in 45% yield as detected by GC–MS and 1 H NMR methods (Table 1, entry 1). Then various palladium salts were investigated for this reaction under similar reaction conditions. Similar yields ...
