Dichloromethyl phenyl sulfone
R. Chan-Yu-King, J. Anil, C. Y. Meyers and P. D. Robinson
Abstract: The unequivocal structure of dichloromethyl phenyl sulfone, C7H6Cl2O2S, (I), via X-ray analysis is reported for the first time. Prepared from the reaction of sodium benzenesulfinate with chloroform in KOH, (I) exhibited a sharp melting point, 331.5-332.0 K. Several different melting points have been reported. We find that (I) crystallizes as two chemically identical molecules in the asymmetric unit, but with a number of small geometric differences between the two molecules. Intermolecular Cl2C-H
O-S(O)-Ph hydrogen bonding between the two geometrically different molecules produces infinite molecular chains, which may induce the small geometric differences exhibited in the two molecules of (I).
