[CHsCeHjj+IAljCb]-.在Friedel-Craft反应过程中形成的络合物被认为是这种碳正离子盐。认为卤化铝在这些Friedel-Craft络合物中的高溶解度是由于形成了一系列此类较高的络合物，通式为R+[A1X<；·？A1X，]~。进一步提出，这些络合物在大多数Friedel-Craft反应中起着重要的作用，因为它们提供了一个高极性的介质，离子中间体可以在其中形成和反应。
[CHsCeHjJ+ IAljCb]-. The complexes which form in the course of Friedel-Crafts reactions are believed to be carbonium ion salts of this kind. It is proposed that the high solubility of aluminum halides in these Friedel-Crafts complexes is due to the formation of a series ofhigher complexes of this kind, with the general formula R+[A1X<·«A1X,]~. It is further proposed that these complexes play an important role in most Friedel-Crafts reactions by furnishing a highly polar medium in which the ionic intermediates may form andreact.
