    • General Experimental Procedure The arylboronic acid (0.3 mmol, 1.5 equiv) was dissolved in anhyd toluene (2 mL) in a 20 mL flame-dried Schlenk reaction tube under argon atmosphere. A commercially available 1 M solution of Me3Ga in toluene (0.9 mmol, 4.5 equiv) was added via syringe dropwise, and the resulting mixture was stirred for 2 h at r.t. followed by the addition of aldehyde (0.2 mmol, After completion of the reaction (monitored by TLC, the reaction solution was quenched with H2O (3 mL) and further extracted with EtOAc (3 x 5 mL, The combined organic layer was dried over Na2SO4. Evaporation of the solvent gave the crude product, which was further purified by preparative TLC (PE-EtOAc, 5:1) to give corresponding pure diarylmethanols
