苯甲醛,3-氯-2 - [(苯基甲基)硫基] -

反应条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a suspension of 112.1 g of potassium-t-butoxide in 1000 mL of dimethylformamide under a nitrogen atmosphere, 124.3 g of benzylmercaptan was added dropwise while maintaining the reaction temperature at 20°-25° C. with an ice-water bath. After stirring at 25° C. for 1.5 hours, a solution of 175 g of 2,3-dichlorobenzaldehyde dissolved in 750 mL of N,N-dimethylformamide was added dropwise, while maintaining the reaction temperature at 25°-40° with a water bath. After stirring at 25° C. for 12 hours, the reaction mixture was poured onto excess ice water to yield a precipitate. The suspension was filtered, and the isolated solid was washed with water, suction-dried and finally dried in vacuo at 40° C. overnight to afford 201 g of the title compound as a light yellow solid; m.p. 65°-68° C. while maintaining the reaction temperature at 20°-25° C. with an ice-water bath was added dropwise while maintaining the reaction temperature at 25°-40° with a water bath After stirring at 25° C. for 12 hours to yield a precipitate The suspension was filtered the isolated solid was washed with water suction-dried finally dried in vacuo at 40° C. overnight
