Abstract

Some 1,3,4‐oxadiazol‐2(2__H__)‐ones with aliphatic substituents in 5‐position are prepared in good yields and converted via the 3‐hydroxymethyl derivatives to the corresponding 3‐chloromethyl derivatives which are suitable starting materials for the preparation of insecticidal O,O‐dialkyl‐S‐[(5‐subst.‐1,3,4‐oxidiazol‐2(3__H__)‐one‐3‐yl)‐methyl]‐thiophosphates and dithiophosphates.
