PROCESSES FOR THE PREPARATION OF 2-THIOPHENECARBONYL CHLORIDE

摘要

Provided herein are processes for the preparation of 2-thiophenecarbonyl chloride, which is useful, for example, in the preparation of 3,5-disubstituted-1,2,4-oxadiazoles, such as tioxazafen (3-phenyl-5-(2-thienyl)-1,2,4-oxadiazole).
