Treatment of trityl ether with a mixture of trifluoroacetic acid, 2,2-dimethoxy propane and camphor- sulfonic acid as catalyst in dichloromethane through detritylation followed by acetonization gave the ace- tonide in high yield.

介绍了一种新的高效的由三苯甲基醚直接生成丙酮化合物的方法,也就是使三氟乙酸条件下脱三苯甲基的反应和生成丙酮化合物的反应在一个反应瓶中同时进行,使脱三苯甲基作用后生成的醇继续反应得到高产率的丙酮化合物。

The decarbonylation and the surface reaction of mixed cluster Ru3(CO)12-Fe2 (CO)9 supported on ZrO2 or Al2O3 have been studied by IR spectroscopy and TPDE-GC technique.

混合族在真空中随温度升高而发生脱羰基作用，５００℃左右羰基完全脱掉；以Ａｌ２Ｏ３为载体者其羰基不易脱除，升高温度出现多种羰基带。
