A catalytic process for trifluoromethylation of terminal alkynes with Togni’s reagent has been developed, affording trifluoromethylated acetylenes in good to excellent yields. The reaction is conducted at room temperature and exhibits tolerance to a range of functional groups.
已经开发出用Togni试剂催化末端炔烃的三氟甲基化的催化方法,从而以良好或优异的收率提供了三氟甲基化的乙炔。该反应在室温下进行,并且表现出对一定范围的官能团的耐受性。
