Homolytic addition of thiophenol to ethyl (Β-phenylthio)crotonate
- 24 Downloads
When initiated by either peroxide or photochemically, thiophenol adds to ethyl (Β-phenylthio)crotonate to give ethyl Β,υ-bis(phenylthio)butyrate. The homolytic allylic isomerization of the unsaturated ester with hydrogen migration was postulated.
In contrast to the dibutylmercaptol of acetoacetic ester, the diphenylmercaptol of acetoacetic ester fails to undergo rearrangement with 1,2-migration of the phenylthio group.
