Abstract
NEW MATERIAL:Benzoxazole compound of formula I (X1,2 are alkyl, halogen, trihalogenomethyl; R is β-halogenoethl, lower alkynyl).
EXAMPLE: 5,6-Dichloro-2-propargylthiobenzoxazole.
USE: Herbicide. Harmless to soybean and peanut. Effective to various weeds such as large carb-grass, green foxtail, jointweed, smooth pigweed, common purslane, hairy galinsoga, etc., by treating the soil from beginning of the sprouting to the initial stage of growing.
PROCESS: The compound II which is one of the objective compound I, is prepared, e.g. by dissolving and reacting 2-amino-4,5-dichlorophenol with potassium ethylxanthate to a mixed solvent of water and ethanol, and reacting the 5,6-dichloro-2- mercaptobenzoxazole potassium salt with propargyl bromide in ethanol under reflux.
