Triphenylmethyl chloride can react selectively with the 30-hydroxil group of glycyrrhetol under the catalyzing effects of three ethyl amine and dimethyl amino-pyridine.This condition of the reaction has an important value for the selective protection of 30-hydroxil group of glycyrrhetol.

三苯氯甲烷在三乙胺和二甲氨基吡啶等碱性催化下与甘草萜醇的C30-位羟基进行选择性缩合反应，此反应产率较与C3-位羟基化反应的要高，此种反应条件在甘草萜醇C30-位羟基的选择性保护中具有重要的价值。

Molybdophopsphoric Acid Catalysis in the Oxidative Cleavage of Olefins by the Hydrogen Peroxide Oxidative cleavage of the double bond could be catalyzed by H_3PMo_(12)O_(40) using H_2O_2 as oxidant, various trisubstituted olefins were oxidized to aldehydes or ketones in high yields. The system was not satisfied for electron-deficient olefins such as trans-(2-nitrovinyl) benzol or chalcone. The reaction of aliphatic olefins did not occur under the same conditions.

二、磷钼酸催化过氧化氢对烯烃的氧化断裂反应用过氧化氢(30％)作为氧化剂，磷钼酸可以催化氧化碳碳双键的断裂反应，三取代的烯烃被氧化生成醛或酮，产率较高；此体系对于缺电子烯烃如查尔酮，不饱和硝基化合物的断裂反应效果较差，脂肪族烯烃在此体系下的氧化并不发生。
