Merrifield-bound o-cresol undergoes electrophilic aromatic chlorination using SO2Cl2 leading to para/ortho ratios in excess of 50, the highest such ratio reported for this chlorinating agent. Model studies suggest that this significant para/ortho ratio results not just from steric effects but that considerable electronic influence can be detected. (C) 2002 Elsevier Science Ltd.
