Synthesis of a new a-aminophosphonate library. Crystal structure ofp-XC_6H_4-NH-CH(p-BrC_6H_4)-P(0)(OiPr)_2(X = H, Br, CH_3O)

摘要

A new library of a-aminophosphonates of thecommon formula R~1NH-CH(R)-P(0)(OiPr)_2, containingsubstituted phenyl and pyridine groups R and R~1, weresynthesized and characterized by IR, ~1H, ~(31)Pspectroscopyand elemental analysis. Crystal and molecular structuresof three a-aminophosphonates p-XC_6H_4-NH-CH(p-XC_6H_4)-P(O)(OiPr)_2(X = H, Br, CH_3O) were establishedby single crystal X-ray diffraction.
