Phosphonic acids — X steroidal phosphonic esters

Steroids, 1967
Abstract Steroidal phosphonate esters having the dialkoxyphosphinyl group, (RO) 2 P(O)-, as a ring substituent have been synthesized via reaction of the appropriate α, β-unsaturated ketosteroid with trialkyl phosphite in alcohol. By this means a phosphorus substituent has been introduced into the 1-positions of testosterone, hydrocortisone, and ...

Ethylenebis(phosphonic acid)

Acta Crystallographica Section C Crystal Structure Communications, 1999
The as yet structurally uncharacterized title compound, C 2 H 8 O 4 P 2 , was isolated as a by-product of the synthesis of 1,2-bis(dimethylphosphino)ethane (dmpe) from 1,2-bis(dichlorophosphino)ethane. In the crystal structure, which is characterized by strong intermolecular O-H…Osp 2 hydrogen bonds, only the R * ,S * diastereomer is found.
