Thionyl Chloride → 4-Phenylbenzoyl chloride

Participants

Reaction Steps

(1,1′-biphenyl)-4-carboxylic acid (20 g, 100.9 mmol) was refluxed for one night in 100 ml of SOCl2 in the presence of a few drops of DMF. Thionyl chloride was removed at ordinary pressure and the residue was triturated in Et2O and filtered. Yield 100% of (1,1′-biphenyl)-4-carbonyl chloride (21.9 g), white crystalline solid. m.p. 116-119° C. 1H-NMR(CHCl3) 7.41-7.73 (7H, m), 8.18 (2H, d, J=8.3 Hz). 13C-NMR(CHCl3) 128.0, 128.1, 129.5, 129.7, 132.4, 132.6, 139.6, 148.7, 168.6
