A systematic investigation was made of the catalytic effect of different substances on complexation of toluene with Cr(CO)6. 1-3 molar equivalents of butyl acetate in refluxing decalin was found to be the best catalyst, providing that the complexation was carried out in a special apparatus described earlier.Comparable yields were obtained also in butyl acetate as a solvent, but the reaction time was more than doubled.The utility of the method was verified by complexation of 7 different benzene derivatives.
