Markovnikov-Selective addition of fluorous solvents to unactivated olefins using a co catalyst

Abstract

We developed an addition reaction of fluorous solvents to olefins using salen-cobalt (Co) complex, Nfluoro- 2,4,6- Trimethylpyridinium tetrafluoroborate, and 1,1,3,3- Tetramethyldisiloxane. This reaction condition was found to activate olefins, which enabled them to be attacked by 2,2,2- Trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), both of which are electronically weak nucleophiles.
