Abstract

Abstract Tetrakis (trialkylsilyl) diphosphate (alkyl= Me, Et, iPr, tBu) can be obtained in quantitative yield by reacting commercial disodium dihydrogen diphosphate with the respective trialkyl chlorosilane in a triphasic system with formamide. The alkylsilane residues of the diphosphate silyl esters can be either partially or completely hydrolyzed without concurrent cleavage of the P–O–P bond of the diphosphate moiety. The method ...
