Reaction Conditions:
in acetonitrile at 20; for 12 h;UV-irradiation;
Steps:
Photoinduced Arylborylation; General Procedure
General procedure: A solution of arylazo sulfone 1 (0.10 mmol) and the respective diboron 2 (0.20 mmol, 2.00 equiv) in degassed MeCN (2.00 mL, 0.05 M) was poured into a glass vessel, capped, and exposed to blue light (H150 Kessil lamp, 34 W, 420 nm) at r.t. for 12 h. After the completion of the reaction (detected by TLC), the solvent was removed in vacuo and the crude product was purified via column chromatography on silica gel.
