reagents react with car☐ylic chlorides, in THF between 0 and 10°C, to give the corresponding ketones in highyields. The scope of the reaction is very large; alkyl, alkenyl and aryl magnesium reagents have been used successfully. The selectivity of the reaction allows to prepare various fonctionalized ketones from car☐ylicacid chlorides bearing a functional group (Cl, Br, ester nitrile and even a ketone)
在催化量的氯化锰(3%MnCl 4 Li 2)的存在下,有机镁试剂在0至10°C之间的THF中与羧基氯化物反应,以高收率得到相应的酮。反应范围非常大。烷基,烯基和芳基镁试剂已成功使用。反应的选择性允许从带有官能团(Cl,Br,酯腈甚至是酮)的汽车☐酰氯制备各种功能化的酮。
