reactions with a 1:1 complex of n-butyllithium and tetramethylethylenediamine to give moderate to high yields of phosphinomethyllithium compounds. This method of preparation enjoys several advantages over the known method. The utility of phosphinomethyllithium compounds as intermediates in the synthesis of carbon-functionally substituted organophosphines has been demonstrated by the conversion of (diphenylphosphino)
