摘　　要：报导了用手性季铵盐诱导合成 SFe Co Mo等手性四面体过渡金属簇合物的新方法 .发现 ,苄基辛可宁对四面体簇的合成有手性诱导作用 ;在不同溶剂中 ,手性簇产物的绝对构型不同 ,而且含钌簇的旋光度比含铁簇的旋光度小 .Three series of chiral metal clusters induced by two kinds of phase\|transfer catalysts have been synthesized. Benzyl cinchonium chloride is active to all kinds of metal clusters under all sorts of conditions. Ether is found to be the most suitable solvent, and the enantiomer obtained is different if the synthesis was proceeded in different solvents. Unfortunately, the e.e. value was not obtained, so only some tentative conclusions were postulated.
