Bis(dialkylphosphino)amines HN(PR2) 1  are reliable precursors to the monoanionic bis(dialkylphosphino)amido ligand [N(PR2)2]. This ligand is ambidentate, and is known to bond in a variety of modes with either transition metal or lanthanide and actinides compounds. The coordination chemistry of this important ligand class with main group elements is not as explored extensively and our group has been successful in using these ligands to prepare novel tin containing compounds that react with carbon dioxide. Bis(dialkylphosphino)amines HN(PR2)2 have the ability to engage in tautermerization reaction generating a phosphorane 2  . Here we report the use of 1  to prepare an stable frustrated Lewis pair system capable of reacting with carbon dioxide.
