Carbonylation of polyfluorinated benzocyclobutenes with CO in an SbF5 medium readily proceeds at room temperature and atmospheric pressure and it is followed by four-membered ring transformations. Perfluorinated benzocyclobutene, 3- and 4-methyl-benzocyclobutenes add two CO molecules to form, after ring opening and following heterocyclization, isochromene derivatives. Hydrolysis of the reaction mixtures
在SBF与CO多氟化苯并环丁烯的羰基化5介质容易进行在室温和大气压的压力和它后面是四元环转换。全氟化的苯并环丁烯,3-和4-甲基-苯并环丁烯添加两个CO分子的形式,开环和以下heterocyclization,苯并吡喃衍生物后。该反应混合物的水解得到相应的4-羧基-1- ħ -isochromenes和2-(羧甲基)苯甲酸。全氟化1-甲基,1-乙基和1-异丙基-苯并环丁烯的羰基化后者的水解之后给出2-(2-甲基苯基)烷基-2-烯酰基阳离子的盐和相应的酸。全氟-1- phenylbenzocyclobutene与CO-的SbF反应5 变换成全氟-4- phenylisochromenyl阳离子的盐,其水解得到全氟-4- phenylisochromen -1-酮。
