    • PROBLEM TO BE SOLVED: To provide an acid catalyst which can reduce the quantity of waste in an organic synthesis reaction and which does not corrode a reactor and is nontoxic.SOLUTION: A phenolic compound having a bis(trifluoromethanesulfonyl)ethyl group is used. The compound can be utilized as a catalyst in various organic chemical reactions, particularly in organic synthesis reactions such as Diels-Alder reaction, Friedel-Crafts reaction, Michael addition reaction and esterification reaction. This acid catalyst exhibits higher activity compared with the conventional Lewis acid, and accordingly need not be used in a stoichiometric amount. Namely, the acid catalyst enables, even when an extremely small amount of the catalyst is used, a desired organic reaction to proceed. Further, the acid catalyst is soluble in various solvents and thus enables homogeneous reaction, and further the acid catalyst can be easily and simply separated from an objective product after the completion of reaction. A reaction can be carried out at a relatively low temperature near ordinary temperature. A method of using the compound is highly useful also as an industrial manufacturing process.
    • 要解决的问题:提供可以减少有机合成反应中的废物量并且不会腐蚀反应器并且是无毒的酸催化剂。 解决方案:使用具有双(三氟甲磺酰基)乙基的酚类化合物。 该化合物可用作各种有机化学反应中的催化剂,特别是在有机合成反应如狄尔斯 - 阿尔德反应,Friedel-Crafts反应,迈克尔加成反应和酯化反应中。 与常规路易斯酸相比,该酸催化剂具有更高的活性,因此不需要以化学计量的量使用。 也就是说,即使使用极少量的催化剂,酸催化剂也能够进行期望的有机反应。 此外,酸催化剂可溶于各种溶剂,因此能够均匀反应,并且在反应完成后,酸催化剂可以容易且简单地与目标产物分离。 反应可以在常温附近的较低温度下进行。 使用该化合物的方法也可用作工业制造方法。 版权所有(C)2012,JPO&INPIT
