Participants

Reaction Steps

4-Chlorobenzaldehyde (144 mg, 1.02 mmol) reacted with phenylboronic acid (185 mg, 1.36 mmol) using 1/2 mol % of Pd(OAc)2/Ph5FcP(t-Bu)2 and KF (178 mg, 3.18 mmol) in THF at 50° C. to give the title compound (180 mg, 96%) as a colorless oil: 1H-NMR (400 MHz, CDCl3): δ 8.05 (s, 1H), 7.96 (d, 2H, J=8.32 Hz), 7.76 (d, 2H, J=8.22 Hz), 7.65 (d, 2H, J=7.08 Hz), 7.52-7.14 (m, 3H). 13C{1H}-NMR (100 MHz, CDCl3): δ 191.88, 147.10, 139.62, 135.11, 130.21, 128.96, 128.42, 127.61, 127.30. GC/MS(EI): m/z 182 (M+), 152. Anal. Calcd for C13H10O: C, 85.69; H. 5.53. Found: C, 85.69; H, 5.77.
