Abstract
Abstract The products obtained by the reaction of fluorine with various tolanes in freon 11 include 1,1,2,2-tetrafluoro-1,2-diarylethanes, cis - and trans - α,α′-difluorostilbenes, 1,2,2-trifluoro-1,2-diarylethanes, 1,2,2,2-tetra- fluoro-1,1-diarylethanes, and 1,1-difluoro-2,2-diarylethenes. The 1,1,2,2- tetrafluoroethanes predominate at −78°C, while the α,α-difluorostilbenes predominate at 0°C. The relative rates of formation of the tetrafluorides and α,α-difluorostilbenes have been determined and show only a small substituent dependence.
