摘要：

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 degrees C, I atm from n-butane and CO after water (or alcohol) treatment in approximate to 90% yield based on the superelectrophilic system. Pentane reacts with CO in the presence of the CBr4. 2AlBr(3) superacid to give a single product, EtC(Me)(2)COOR, in almost quantitative yield. (C) 1999 Elsevier Science Ltd. All rights reserved.
