Solutions of DL-alanine, DL-valine, DL-leucine and DL-isoleucine in water containing mercury (II) chloride were irradiated for 4 hr by an 8W low-pressure mercury arc lamp. The alkylmercury (II) chlorides produced in the irradiated solutions were analysed quantitatively by gas chromatography. It was observed that methylmercury unrelated to the alkyl residues in the α-amino acid was formed almost exclusively, although DL-leucine yielded an undetermined organomercury compound in addition to methylmercury. The use of a 20W blacklight lamp (300-400 nm) as a light source resulted in the formation of a much lower yield of methylmercury after irradiation for 150 or 300 hr. A white solid deposited as the reaction proceeded showed some properties of a mercurous compound. Photolysis of glycine and phenylglycine did not yield alkylmercury compounds, indicating that the formation of methylmercury was due to the apparent fragmentation of the alkyl residues of the α-amino acid during photolysis.
