Yield: 55%

Reaction Conditions:

in 2,2,2-trifluoroethanol;acetone for 24 h;Inert atmosphere;Irradiation;

Steps:

General procedure for the preparation of biaryls 2 and 4
General procedure: A solution of the chosen triarylphosphate 1 or of the ethyl (diaryl) phosphate 3 (0.02 M) in a CF3CH2OH/acetone 4:1 mixture(10 mL) was argon saturated, then irradiated by means of a multilamp reactor (a Rayonet-likereactor purchased by Helios Italquartz, Italy) equipped with 10 phosphor-coated Hg lamps (15W, em = 310 nm)7 for 24 hours. The photolyzed solution was then evaporated and the residuepurified via column chromatography (eluent: petroleum ether/ethyl acetate mixture).
