HERBICIDALLY ACTIVE 2-NITRO-5-PHENOXYPHENYLOXAZOLES, - OXAZINES, -IMIDAZOLES, -PYRIMIDINES AND -THIAZOLES, AND THE PRODUCTION AND USE THEREOF

摘要

AbstractNovel 2-nitro-5-phenoxyphenyloxazoles, -oxazines and -thiazolesare disclosed. These compounds have the formula(I)wherein A is a C2-C3alkylene or C2-C3alkenylene radical which can besubstituted by C1-C4alkyl or C1-C4haloalkyl, each of R1, R2 and R3independently is hydrogen, halogen, trifluoromethyl, nitro orcyano, and X is oxygen, sulfur or an imino group. The novel compoundshave herbicidal and plant growth-inhibiting properties. They areespecially suitable for use as selective herbicides in crops ofcereals.
