1,4-dihydro-3H-2-benzopyran-3-one → (2-Hydroxymethylphenyl)acetonitrile
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1,4-dihydro-3H-2-benzopyran-3-one | HCID 78092 | — |
| Reactant | 2-(Cyanomethyl)benzyl chloride | HCID 11298159 | — |
| Product | (2-Hydroxymethylphenyl)acetonitrile | HCID 582335 | 1.6% |
Reaction Steps
After completion of the reaction, the concentration of 3-isochromanone was analyzed by GC analysis and then the yield of 3-isochromanone was calculated. As a result, the yield was found to be 95% based on α-chloro-α′-cyano-o-xylene. At this time, the conversion ratio of α-chloro-α′-cyano-o-xylene was 100% and the by-product compound (α-hydroxy-α′-cyano-o-xylene) where the halogen moiety was hydrolyzed was produced in a yield of 1.6%.
