5-Formylimidazo[2,1-b]thiazoles and derivatives with herbicidal activity

Abstract

A series of imidazo[2,1- b ]thiazole derivatives including aldehydes ( I-XXIX ), oximes ( XXX-XL ) and 2,4-dinitrophenyloximes ( XLI-LIII ) were prepared and tested as potential herbicides. Many compounds were active in paddy field treatment, sand and in water culture. In upland condition, a number of dinitrophenyloximes proved herbicides in postemergence treatment, whereas in preemergence only compounds XVI, XXV and XLVIII showed some degree of activity.
