Abstract
PURPOSE: To prepare the title compound useful as a soil disinfectant, in high purity and yield, by reacting a phenol with O,O-dimethylthiophosphoric acid chloride in an aqueous solution of alkali hydroxide, in the presence of a copper catalyst.
CONSTITUTION: The objective compound II is prepared by reacting a phenol of formula I (X1, X3 are halogen; X2 is methyl, ethyl) with O,O-dimethylthiophosphoric acid chloride in an aqueous solution of an alkali hydroxide (pref. 10-40% solution of NaOH, KOH, etc.), in the presence of a Cu-containing catalyst (e.g. copper sulfate, copper nitrate, cuprous chloride, copper carbonate, etc., especially preferably metallic copper powder) at 0-80°C for 1-5 hours.
