- The first examples of selective carbonylation of n-butane and n-pentane
-
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.
