Abstract
The kinetics and mechanism of addition of dialkyl hydrogen phosphites and their fluorinated analogs to ethyl benzoylformate was studied for the first time by spectrophotometry. The kinetic and activation parame ters of the reactions studied were determined. The inversed reactivity order in the series of dialkyl hydrogen. phosphites was found, the re activities of fluorinated and nonfluorinated dialkyl hydrogen phosphit es being similar. The reactivity of dialkyl hydrogen phosphites in the se reactions is governed by the stereoelectronic effect of substituent s at the phosphorus atom.
