Reactions of ethyl trimethylsilyl (diethoxymethyl)phosphonite with carbonyl compounds
The authors proposed a convenient method for the synthesis of silicon-substituted (dialkoxymethyl) phosphonites. In the present work the authors show that these compounds, which contain an Si-O-P fragment in the molecule, can be used for the synthesis of functionally substituted (dialkoxymethyl)phosphinates containing silicon. Thus, ethyl trimethylsilyl (diethoxymethyl)phosphonite, like silyl phosphites, adds smoothly in methylene chloride solution at the carbonyl group of benzaldehyde or butyraldehyde with the formation of the phosphinates. The IR spectra were determined on an IKS-22 spectrometer (NaCl), the PMR spectra on a Tesla BS-467 spectrometer (standard TMS), and the /sup 13/C and /sup 31/P NMR spectra on a JEOL FX-100 spectrometer with TMS (/sup 13/C) and an 85% solution of H/sub 3/PO/sub 4/ in D/sub 2/O as standards.
