Reaction Steps

A solution of 280 parts of o-xylyl chloride in 520 parts of benzene is added to a mixture of 520 parts of benzene and 200 parts of boron fluoride/phosphoric acid (containing 90 parts of boron trifluoride in 110 parts of phosphoric acid) at from 75° to 80°C in the course of one hour. The reaction mixture is stirred for a further three hours at 80°C and allowed to cool, the aqueous solution is separated off and the organic phase is distilled. Yield 322 parts (88.4% of theory) of o-benzyltoluene of boiling point from 145° to 149°C at 17 mm Hg.
