Procedure
A solution of 70 parts of xylyl chloride in 240 parts of benzene is added to a mixture of 60 parts of boron fluoride dihydrate and 250 parts of 75 per cent strength by weight sulfuric acid at from 75° to 78° C, whilst stirring vigorously. After 6 hours, the organic phase is separated off and 82 parts (91.1% of theory) of o-benzyl-toluene boiling at 98° C at 0.2 mm Hg are isolated by distillation.
