arylation reaction using α-aryl isopropenyl-tert-cyclobutanols has been developed. This reaction gives access to benzodiquinanes in moderate to good yields and tolerates alkyl-, alkoxy-, and halogen-substitutedaryl groups.

Novel copper/B2pin2-catalyzed difluoroalkylation of methylenecyclopropanes with bromodifluorinated acetates and acetamides via a tandem radical process involving ring-opening/intramolecular cyclization has been reported. This protocol is not only tolerated to a diverse range of substrates but also applicable to the synthesis of useful difluoromethylated compounds. Moreover, the reaction could be performed
已经报道了经由涉及开环/分子内环化的串联自由基过程的新型铜/ B 2 pin 2催化的亚甲基环丙烷与溴代二氟乙酸盐和乙酰胺的二氟烷基化。该方案不仅可耐受多种底物,而且可用于合成有用的二氟甲基化化合物。此外,该反应可以以克的规模高产率地进行,这为实际应用开辟了可能性。
