strategy for aromatic trifluoromethylation by converting amino into trifluoromethyl groups via a Sandmeyer-type reaction is reported. The transformation involves diazotization of the aromatic amines with tert-butyl nitrite and hydrochloric acid to form aryldiazonium chlorides, followed by trifluoromethylation with trifluoromethylsilver at low temperature. Various readily available aromatic amines are
摘要 报道了通过Sandmeyer型反应将氨基转化为三氟甲基的芳香族三氟甲基化的新策略。该转化包括用亚硝酸叔丁酯和盐酸将芳族胺重氮化以形成芳基重氮氯化物,然后在低温下用三氟甲基银进行三氟甲基化。各种容易获得的芳族胺在温和条件下均能平稳转化。 报道了通过Sandmeyer型反应将氨基转化为三氟甲基的芳香族三氟甲基化的新策略。该转化包括用亚硝酸叔丁酯和盐酸将芳族胺重氮化以形成芳基重氮氯化物,然后在低温下用三氟甲基银进行三氟甲基化。各种容易获得的芳族胺在温和条件下均能平稳转化。
