Abstract

The 31 P NMR spectrum of the reaction mixture of phosphinoyl chloride Ia and phosphoroamidite II contains signals of trimethylsilyl phosphinate VIa (dP 26 ppm), bis (chloromethyl) phosphinous chloride (IIIa)(dP 98 ppm), and residual phosphoramidite II. The experimental evidence obtained suggests that the first stage of the reaction involves oxidation of phosphoroamidite II to diethyl trimethylsilyl (trimethylsilyl) phosphorimidate (IV ...
