Phenylboronic Acid → 4-Phenylbenzene-1-sulfonamide

Participants

Reaction Steps

Using preparation method 2, 4-bromobenzenesulfonamide (472 mg, 2 mmol) was reacted with phenylboronic acid (268 mg, 2.2 mmol). Purification by washing with hot toluene followed by filtration gave 4-phenylbenzenesulfonamide as an off-white crystalline solid (264 mg, 55%). NMR 1H (ppm, CDCl3): 7.87 (d, J3=8.6 Hz, 2H), 7.83 (d, J3=8.7 Hz, 2H), 7.70 (d, J3=7.2 Hz, 2H), 7.48 (t, J3=7.3 Hz), 7.40 (t, J3=7.1 Hz, 1H).
