Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 1-Chloro-2,3-dimethylbenzene | HCID 32884 | — |
| Reactant | Boron trifluoride dihydrate | HCID 61591 | — |
| Solvent | Benzene | HCID 241 | — |
| Product | 2-Benzyltoluene | HCID 69738 | 91.1% |
Reaction Steps
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.
