Abstract

Abstract Some 1, 3, 4-oxadiazol-2 (2H)-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 (3H)-one-3-yl)-methyl]- thiophosphates and dithiophosphates.
