Explanation

The oxidation of aromatic methyl groups to aldehydes with cromyl chloride (CrO2Cl2) is known as Etard reaction. The reaction of triphenylphosphine and tetrahalomethanes (CCl4, CBr4) with alcohols is a ready method to convert an alcohol to the corresponding alkyl halide under mild conditions in high yields. This reaction is known as Appel reaction.
