The use of α,α-dichlorodiphenylmethane as chlorinating agent and FeCl3 as the catalyst enables a chlorination of alcohols and carboxylic acids to their corresponding alkyl and acyl chlorides in high yields under mild conditions. In the presence of LiBr or LiI, the respective alkyl bromides and iodides can be generated.
