    • Standard procedure for Suzuki-Miyaura in PTS/water. 4-Methoxy-2′-methylbiphenyl (23; Table 4, entry 4, To a 5 mL round-bottom flask was added a 15 mm long prolate spheroid magnetic stir bag. 5 (6 mg, 0.009 mmol, and 4-methoxyphenylboronic acid (114 mg, 0.75 mmol, Under a positive flow of argon while stirring were added each via syringe Et3N (0.21 mL, 1.5 mmol, aqueous PTS (1% w/w, 2 mL, and 2-chlorotoluene (60 μL, 0.51 mmol, The reaction was stirred at rt and conversion was monitored by GC. After 24 h the contents of the flask were diluted with brine and extracted three times with ethyl acetate. The solution obtained was dried over anhydrous MgSO4, filtered, and concentrated by rotary evaporation. The solid residue was purified by flash chromatography eluting with a gradient from 1/99 to 5/95 diethyl ether/petroleum ether to afford the product biaryl (86 mg, 85, as a white solid; 1H NMR (400 MHz, CDCl3) matches p
