Process for preparing 3-isochromanone |
| abstract |
3-Isochromanone is prepared by contacting an o-xylene-α,α′-dihalide with carbon monoxide in a two-phase liquid medium, in which one phase is aqueous and the other phase is water-immiscible, in the presence of a catalyst and a hindered amine base. |
