Abstract

Using CO(PPha)Cl2 as catalyst, the carbonylation of benzyl halide with CO (1 atm) in a binary system (aq.NaOH/CsHs in the presence of tetrabutylammonium bromide as phase transfer catalyst for 10 h gives the corresponding carboxylic acid in good to excellent yields. The effects of phase transfer catalyst and reaction temperature on the reactions have been investigated. The reaction mechanism is briefly discussed.
