Abstract
Abstract 5-Ethylthio-1- H -tetrazole (SET) and 4,5-dicyanoimidazole (DCI) were examined as alternatives to 1- H -tetrazole to mediate the synthesis of phosphonate diesters and phosphonamidates from phosphonyl dichlorides through a two-step one-pot reaction in various organic solvents. SET and DCI were comparable to 1- H -tetrazole for catalyzing these reactions. SET afforded slightly greater yields than DCI while benzene was universally the best solvent for this reaction.
