Reactions of Iso(thio)cyanato Derivatives of Three- and Four-Coordinate Phosphorus with Trimethylsilyldiethylamine

Iso(thio)cyanato(thio)phosphates (-phosphonates, -phosphinates) take up trimethylsilyldiethylamine to form phosphorus- and silicon-containing (thio)ureas. Simultaneous introduction to the phosphorus atom of an urea (thiourea) moiety and a chloromethyl group, followed by intramolecular cyclization under the action of a base, yields 1,3,4-oxaza(thiaza)phospholines. Linear and cyclic P(III) isothiocyanato derivatives react with trimethylsilyldiethylamine with substitution of the isocyanato group by a diethylamino group and formation of the corresponding phosphoramidites.
