Title: Brian K. Riley: Innovator in Herbicidal Chemistry
Introduction
Brian K. Riley is a notable inventor based in Santa Rosa, California. He has made significant contributions to the field of herbicidal chemistry, holding a total of 5 patents. His work focuses on developing innovative compounds that are effective in controlling undesirable vegetation.
Latest Patents
Among his latest patents are the herbicidal 12-substituted 12H-dibenzo[d,g]dioxocin-6-carboxylic acids. These compounds are substituted by methyl or ethyl or a moiety --CH₂CH₂-- at the 12-position and can be further modified at other positions. They include methyl 4'-chlorospiro(cyclopropane-1,12'(12'H)-dibenzo[d,g][1,3]dioxocin)-6'-carboxylic acid, along with their agriculturally acceptable esters, amides, and salts. These innovations are particularly useful for controlling unwanted plant growth. The necessary 1,1-diarylcyclopropane intermediates for these spirocyclopropane compounds can be synthesized from appropriately substituted 1,1-diarylethene precursors through a reaction with phenylthiomethyl lithium reagent.
