A variety of protic 2-(tertiary phosphino)-1-amines (R2PCH 2CHR'NHR", P̃NH) have been prepared from 2-oxazolidinones and secondary phosphines using a newly developed acid-promoted decarboxylatie C-P bond formation reaction. Treatment of the resulting chiral P̃NH compounds with Cp*RuCl(isoprene) in CH2CI2 smoothly furnished chiral Cp*RuCl(P-NH) complexes with a typical three-legged piano-stool structure, which prove to be excellent catalyst precursors for asymmetric reactions, including the isomerization of allylic alcohols and hydrogenation of imides.
