Trichlorocyclopropenylium tetrachloroaluminate 1+-AlCl−4 reacts with alkenes in nitromethane at −35°C to give the 1:1 addition products 2+-AlCl−4, which can be converted into the 2-chlorocyclopropenones 5 or the ä,β-acetylenic carboxylates 6.
三氯环丙烯基四氯铝酸盐1 + -AlCl - 4与烯烃在硝基甲烷中在-35°C下反应,生成1:1加成产物2 + -AlCl - 4,可以将其转化为2-氯环丙烯酮5或ä,β-炔基羧酸盐6。
