摘要:
A process for producing novel 1,4-benzothiazine derivatives (I), ##STR1## (in which X is a halogen atom) and their derivatives, ##STR2## wherein R is a (C.sub.1 -C.sub.5) alkyl, (C.sub.3 -C.sub.6) cycloalkyl, phenyl, substituted phenyl, phenyl (C.sub.1 -C.sub.5) alkyl or phenoxy (C.sub.1 -C.sub.5) alkyl group, and herbicides containing these compounds as an active ingredient. Compound (I) is produced by the reaction between Compound (II) and phosphorus pentasulfide; Compound (II) is produced (1) by the reaction between an aminothiophenol (III), ##STR3## (in which X is a halogen atom), and a halogenated acetic acid, (2) by the ring closure of Compound (VI), (3) by the reduction and ring closure of Compound (VIII), and (4) by the hydrolysis and ring closure of Compound (X); Compound (VI) is produced by the reaction between Compound (III) and a halogenated acetyl halide; Compound (VIII) is produced by the oxidation of Compound (III) followed by reaction with a halogenated acetyl halide; and Compound (X) is produced by the reaction between Compound (III) and a halogenated acetic ester. Compounds (I), (II), (VI), (VIII) and (X) have a herbicidal activity.
