J. Kamenicek et al., SULFANOLYSIS OF TRIS(2-CYANOETHYL)PHOSPHINE CHALCOGENIDES - X-RAY STRUCTURE-ANALYSIS OF OP(CH2CH2CONH2)(3) AND OP(CH2CH2CSNH2)(3), Polish Journal of Chemistry, 71(8), 1997, pp. 1060-1065
Sulfanolysis of tris(2-cyanoethyl)phosphine oxide (chalcogenide) gave
new compounds of tris(2-thiocarbamoylethyl)phosphine oxide (chalcogeni
de) type, alkaline hydrolysis of which afforded sodium salts of tris(2
-carboxyethyl)phosphine chalcogenides. Two compounds, OP(CH2CH2CONH2)(
3) and OP(CH2CH2CSNH2)(3) were studied by X-ray structure analysis. Th
e coordination sphere around phosphorous atom is in both cases approxi
mately tetrahedral.
