A two-step process for the synthesis of aryl and heteroaryl trifluoromethyl ketones from the corresponding aldehydes is described. Trifluoromethyl alcohols were prepared from aryl and heteroaryl aldehydes in excellent yields using catalytic amount of K2CO3. The trifluoromethyl alcohols were then oxidized conveniently and efficiently by o-iodoxybenzoic acid (IBX) under mild conditions to get the desired
描述了由相应的醛合成芳基和杂芳基三氟甲基酮的两步法。使用催化量的K 2 CO 3由芳基和杂芳基醛以极好的收率制备三氟甲醇。然后在温和的条件下,通过邻碘氧苯甲酸(IBX)方便有效地氧化三氟甲醇,得到所需的官能化芳基和杂芳基三氟甲基酮。
