Latest Patents

Among his latest patents is a process for the palladium-catalyzed coupling of a diazonium salt with an olefinic bond. This innovative 'one-pot' process allows for the coupling to occur in the aqueous medium where the diazonium salt is produced, utilizing a carboxylic acid as a solvent. This method enables the production of arylacrylic acids and their esters, such as cinnamates, at low catalyst concentrations without the need to isolate the diazonium salt first. Another significant patent involves the selective hydrogenation of olefins using a modified ruthenium catalyst. This catalyst selectively hydrogenates an olefinic double bond in the presence of another olefinic double bond, with modifiers chosen from compounds containing trivalent nitrogen, trivalent phosphorus, and divalent sulfur.
