The polyhalomethane based superelectrophilic systems allowed us to accomplish the first efficient and selective carbonylation of n-butane and n- pentane with CO. Depending on the nature of the superelectrophilic system, Me3CCOOR or EtCH(Me)COOR (R = H, Alk) can be obtained at -20°C, 1 atm from n-butane and CO after water (α alcohol) treatment in = 90% yield based on the superelectrophilic system. Pentane reacts with CO in the presence d the CBr4 · 2AlBr3 superacid to give a single product, EtC(Me)2COOR, in almost quantitative yield.

Mixed carboxylic α-bromotoluoyl anhydrides were activated by silver tetrafluoroborate through intramolecular cyclization and reacted with alcohols or thiols giving the corresponding esters or thiol esters in good yields with the elimination of phtalide.
