Ten 3-aryl-thiazolin-2-thione derivatives have been designed and synthesized by the reaction of 3-aryl-4-amino- 3H-thiazolin-2-thiones with phenoxyacetyl chloride and the aza-Wittig reactions of 3-aryl-4-amino-5-ethyloxyacyl- 3H-thiazolin-2-thione with phenols. The structures of target compounds have been confirmed by 1H NMR, EI-MS, IR spectroscopy and elemental analyses. The structure of 5-(4-Cl-phenoxy)-3,6-diphenyl-2-thioxo-2,3-dihydrothiazolo[4,5-d]- pyrimidin-7(6H)-one (C1) has been determined by single crystal X-ray diffraction. The results of preliminary bioassay indicated that some compounds possess good herbicidal activity against the roots of Rape and Barnyard grass.

Key words: thiazolin-2-thione, thiazolo[4,5-d]pyrimidine, aza-Wittig reaction, herbicidal activity
