Abstract

A titanocene-catalyzed reductive domino reaction provides gem-difluorobishomoallylic alcohols starting from trifluoromethyl-substituted alkenes and epoxides. Furthermore, diverse 6-fluoro-3,4-dihydro-2H-pyrans have been prepared through derivatization of the cross-coupling products in a single step.
