Abstract
Rhenium pentachloride has been found to be a Lewis acid with an efficient Friedel-Crafts catalytic property. Aromatic rings have been alkylated smoothly with olefins or alkyl halides. By the reaction of ethylene with benzene in the presence of rhenium pentachloride, s-butylbenzene has been obtained as the main product. In the Friedel-Crafts acylation, a quantitative amount of the catalyst has been consumed in the reaction at a low temperature. On the other hand, the acylation reaction at a high temperature can proceed catalytically. Rhenium pentachloride is also active in the oligomerization of olefins, and in the cyclization and oligomerization of acetylenes.
