Versuchsvorschrift
3,4-Dichlorophenylmethanesulfenyl chloride is prepared from the corresponding 3,4-dichlorobenzyl mercaptan in accordance with the procedure of Example I for the preparation of the sulfenyl chloride, except that this reaction is conducted under cooling conditions. The sulfenyl chloride is reacted with the mercaptopyridine-1-oxide as described in Example I, giving an 84% yield of 3,4-dichlorobenzyl 1-oxo-2-pyridyl disulfide having a melting point of 133.0°-134.0° C. and
