摘　　要：合成一种新的联萘结构的硫醚,其在萘环的8,8′-位联有供电子的苯甲酰胺基.研究表明,此催化剂在催化芳醛与对硝基苄溴的环氧化反应中,表现出较高的活性,这可能是由苯甲酰胺基的供电子作用引起的.这一结果对进一步修饰此类硫醚具有指导意义.A new sulfide having a binaphthyl skeleton was synthesized, and two benzoylamino groups, which were electron donating, were respectively bonded on the 8, 8′-carbon atoms of binaphthyl. It was shown that the sulfide exhibited higher catalytic activity in the reaction of aryl aldehydes with p-nitrobenzyl bromide giving epoxides. The relatively high catalytic activity might be due to the electron donating effect of benzoylamino groups on binaphthyl. This result inspired us a clue for further modification of this kind of sulfide.
