Title: **Susan D Thompson: Pioneering Innovations in Herbicide Development**

Introduction

Susan D Thompson, an innovative inventor based in San Leandro, California, has made significant contributions to the field of herbicide development. With a total of three patents to her name, Thompson's work focuses on creating effective intermediates for the preparation of specialized herbicides, underlining her role as a key player in agricultural chemistry.

Latest Patents

Among her notable patents, the latest innovations include the preparation of 5-acylamino-1,2,4-triazole-3-sulfonamides. These compounds serve as essential intermediates for the production of 1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide herbicides. The process entails a meticulous sequence starting from 5-amino-3-mercapto-1,2,4-triazole, involving sequential acylation to produce 5-acylamino-3-mercapto-1,2,4-triazoles, followed by chlorination, and ultimately condensation with substituted anilines to yield the desired sulfonamides.

Thompson also holds a patent for the preparation of 5-amino-1,2,4-triazole-3-sulfonamides. These intermediates play a crucial role in synthesizing substituted 1,2,4-triazolo-[1,5-a]pyrimidine-2-sulfonamide herbicides. This method involves chlorination of 5-amino-3-mercapto-1,2,4-triazole in an aqueous acid medium, producing 5-amino-3-chlorosulfonyl-1,2,4-triazole, which is then condensed with substituted anilines either in the presence or absence of acid scavenging bases.
