Phosphoric Acid → 2-Benzyltoluene

Participants

Reaction Steps

A solution of 70 parts of o-xylyl chloride and 160 parts of benzene is added to a mixture of 170 parts of 85 per cent strength by weight phosphoric acid and 30 parts of trifluoromethanesulfonic acid at from 75° to 78° C, whilst stirring vigorously. After a further 6 hours, the organic phase is separated off and 79 parts (87.7% of theory) of o-benzyltoluene boiling at 98° C at 0.2 mm Hg are isolated by distillation.
