Table 4.
Reactions run on a 0.1 mmol scale to determine 19F NMR yields and run on a 0.5 mmol scale to obtain yields of isolated products.
A small amount of homodimer was inseparable from the desired product.
Yields determined by 19F NMR spectroscopy with 4-trifluoromethoxyanisole as an internal standard. Compounds were isolated by chromatography on silica gel, see the Supporting Information for details.
