在微波作用下,采用高效催化剂体系,于中等极性非质子溶剂中经卤素交换氟化高效制备了系列含氟芳香醛(酮)类化合物,产品收率53·3%~92·6%,反应时间较常规加热最多可缩短80%以上。采用中等极性反应溶剂,还可突出表现出微波对反应促进的“非热效应”,从而大大拓宽了氟化反应溶剂的选择范围。 Under microwave irradiation, a series of fluorinated aromatic aldehydes and ketones were efficiently prepared by halogen exchange fluorination in a moderately polar aprotic solvent with a high efficiency catalyst system. The yield of the products was 53.3% -92.6% The reaction time can be shortened by more than 80% compared with the conventional heating. The use of a medium polarity reaction solvent also highlights the “non-thermal effect” promoted by the microwaves to the reaction, thereby greatly broadening the range of choices for fluorination solvents.
