Fremgangsmåde til fremstilling af estere af α-(O,O-dimethyl-dithiophosphoryl)- eller α-(O,O-diethyl-dithiophosphoryl)-α-phenyl-eddikesyre

Prepn. of dithiophosphates where R = Me or Et R' = straight or branched (1-5 C) alkyl. Higher yields and higher purity of the reaction products, which when R = Me, are less toxic to warm-blooded animals than the same products prepd. acc. to U.S. 2,947,662. Pesticides, esp. insecticides.
