Formation of C-P bonds by addition of dialkyl hydrogen phosphonates and alkyl hydrogen phosphinates to activated ethylenic derivatives.

Abstract

IN the course of a study in these laboratories of new methods for the formation of C—P bonds, the possibility was considered of addition of organic phosphorus compounds of the type to activated ethylenic derivatives. This would offer a new approach to a synthesis of various organic oxyacids of phosphorus. Recently, we have been able to show that the reaction is promoted by basic catalysts, sodium derivatives of hydrogen phosphonates and hydrogen phosphinates being the most effective.
