Procedure
A solution of 140 parts of o-xylyl chloride and 500 parts of benzene is added to a mixture of 162 parts of boron fluoride dihydrate and 16 parts of sulfuric acid monohydrate at from 75° to 78° C, whilst stirring vigorously. After a further 6 hours, the organic phase is separated off and 162 parts (90% of theory) of o-benzyltoluene boiling at 98° C at 0.2 mm Hg are isolated by distillation.
Workup
- customthe organic phase is separated off
