Claims
- 1. A process for the production of 3,5-disubstituted-4-acetoxystyrene which comprises (a) acylating 2,6- disubstituted phenol under suitable catalysis to provide 3,5-disubstituted-4-hydroxyacetophenone, then (b) esterifying the 3,5-disubstituted-4-hydroxyacetophenone to produce 3,5-disubstituted-4-acetoxyacetophenone, then (c) hydrogenating the 3,5-disubstituted-4-acetoxyacetophenone to form 1-(3',5'-disubstituted-4'-acetoxyphenyl)ethanol and then (d) dehydrating the 1-(3',5'-disubstituted-4'-acetoxyphenyl)ethanol to form 3,5-disubstituted-4-acetoxystyrene, wherein each of said 3,5-substitutions are independently C.sub.1 to C.sub.10 alkyl or alkoxy, amino or halogen.
- 2. The process of claim 1 wherein step (a) is conducted by a Fries rearrangement process.
- 3. The process of claim 1 wherein step (a) is conducted by a Friedel-Crafts acylation process.
- 4. The process of claim 1 wherein step (a) is conducted with a hydrogen fluoride catalyst.
