  Facile and eco-friendly synthesis of bis(tetrahydrobenzofuran-2-yl)alkane derivatives catalyzed by H2S04.SiO2 under solvent-free conditions

  摘要：

  A series of bis(2-tetrahydrobenzofuranyl)alkanes were efficiently prepared in high yields (69-98%) from 3-methyl-6,7-dihydrobenzofuran-4(5H)-ones and aldehydes under solvent-free conditions. The eco-friendly condensation reaction was smoothly catalyzed by H2SO4 center dot SiO2 (30% w/w) in three minutes at 90 degrees C, and the catalyst could also be recycled up to nine successive cycles without significant loss in catalytic activity.
