alpha-EWG ketenedithioacetals benzhydrol Carbon-carbon coupling Sulfonic group-functionalize PMO
摘要：

One-pot method for the preparation of well-ordered periodic mesoporous ethylenesilica functionalized in-situ with sulfonic groups (pr-SO3H-PMO) was deployed successfully. The sulfonic groups have been used as a Bronsted acid to catalyze the carbon-carbon coupling reaction of alpha-electron-withdrawing group (EWG) ketene dithioacetal derivatives and benzhydrol. Meanwhile, this series of materials exhibit excellent catalytic performance in the C-C coupling reaction and pr-SO3H-PMO(0.39) possesses highly efficient catalytic performance among the prepared materials, over which the conversion of ketene dithioacetals achieved 98.3% and the yield of the coupling products reached 93.4%. In addition, evidence is presented that the catalytic activity of pr-SO3H-PMO(0.39) material has been recycled up to five times without a significant reduction.
