Synthesis and crystal structure of 2-chloro-1-(3-hydroxyphenyl)ethanone

Abstract

The structure of 2-chloro-1-(3-hydroxyphenyl)ethanone, C8H7ClO2, an α-haloketone is described. The molecule is planar (r.m.s. deviation = 0.0164 Å) and in the crystal, inversion-symmetric dimers are formed as a result of pairs of strong O—H...O and weak C—H...O hydrogen bonds. A brief comparison is made with structurally related compounds deposited in the CSD. In addition, the synthesis and some spectroscopic details are presented.
