Chloromethyl group



In organic chemistry, the chloromethyl group is a functional group that has the chemical formula \sCH2\sCl. The naming of this group is derived from the methyl group (which has the formula \sCH3), by replacing one hydrogen atom by a chlorine atom. Compounds with this group are a subclass of the organochlorines.

The way of introducing a chloromethyl group into aromatic compounds is the chloromethylation by the Blanc reaction.
