PHOTOCHEMICAL PROCESS FOR THE PREPARATION OF 3-((3,3,3-TRIFLUOROPROPYL)THIO)PROPIONIC ACID AND ESTERS THEREOF |
| 摘要 |
3-((3,3,3-Trifluoropropyl)thio)propionic acid and esters thereof are prepared by a photochemical process involving the free radical coupling of 3-mercaptopropionic acid and esters thereof with 3,3,3-trifluoropropene. The ratio of linear to branched isomer is enhanced. |

1. A process for the preparation of 3-((3,3,3-trifluoropropyl)thio)propionic acid or esters thereof (Formula I) wherein R represents H or C1-C4 alkyl which comprises photochemically coupling 3-mercaptopropionic acid or esters thereof (Formula II) wherein R is as previously defined with 3,3,3-trifluoropropene (Formula III) in the presence of 2,2-dimethoxy-2-phenylacetophenone initiator and long wavelength UV light in an inert organic solvent. |
