In the present paper we report on the mechanism of i-butane alkylation by butenes using three types of well defined catalysts. The first type catalysts are composed heteropolyacids supported on a carbon support. The second type catalysts are represented by sulfated zirconia supported on silica. The third type catalysts were prepared with molecular design using alkyl zirconium complexes. Zirconium cations in coordinatively unsaturated state are shown to be responsible for alkylation. Reaction mechanism is suggested, involving carbenium ions and zirconium hydrides generation from i-butane.
