cost-effective method for the preparation of fluoroalkylated compounds has been described by the direct photoexcitation of halofluoroalkanes with blue light absorptivity, enabling the difluoroalkylation of aryl ketones. The methodology has provided an efficient, mild, and catalyst-free synthetic method for quaternary difluoroalkylated arenes and tetrasubstituted monofluoroalkenes.
通过直接光激发具有蓝色光吸收性的卤代氟烷烃,从而实现了芳基酮的二氟烷基化,已经描述了一种制备氟代烷基化化合物的简便且经济高效的方法。该方法为季二氟烷基化的芳烃和四取代的单氟烯烃提供了一种高效,温和且无催化剂的合成方法。
