摘要：
CHLOROTHIAZOLES HAVING THE FORMULA:
2-R2,4-CL,5-R1-THIAZOLE
WHEREIN R1 IS CHLORINE,
-CCL3, -CN, -N=CCL3, OR (CL-)X-PHENYL
WHERE X IS O, 1 OR 2, AND R2 IS CHLORINE,
-CCL3, -CN, -O-((CL-)X-PHENYL) OR (CL-)Y-PHENYL
WHERE X IS AS DEFINED ABOVE AND Y IS A NUMBER FROM 0 TO5 ARE PREPARED BY REACTING COMPOUNDS HAVING THE FORMULA:
R1-C(-Q)(-CL)-C(-Q)(-CL)-N=C(-R2)-CL
WHEREIN R1 AND R2 ARE AS DEFINED ABOVE AND Q IS CHLORINE OR TOGETHER REPRESENT A C-C- BOND; WITH SUBSTANTIALLY THE STOICHIOMETRICALLY NECESSARY QUANTITY OF SULPHUR AT A TEMPERATURE IN THE RANGE OF FROM 150 TO 350*C. SUCH CHLOROTHIAZOLES CAN BE USED FOR THE PRODUCTION OF PLANT PROTECTION AGENTS, ESPECIALLT AS INSECTICIDES.
