The direct catalytic aldol reaction of trifluoromethyl -ketoneswith ketones has been accomplished. The reaction was achieved inthe presence of 10 mol% Et 2 Zn and N, N′-dimethylethylenediamineat ambient temperature to give the expected aldol-type productsin high yields (up to 99%).
完成了三氟甲基酮与酮的直接催化羟醛反应。该反应在环境温度下在 10 mol% Et 2 Zn 和 N,N'-二甲基乙二胺存在下完成,以高产率(高达 99%)得到预期的醇醛型产物。
