Structural Diversity of Lithium, Sodium, and Potassium Complexes of N-Mesityl-P,P-diphenylphosphoryl Amide
Metalation of N-mesityl-P,P-diphenylphosphinic amide Ph2P(=O)-N(H)Mes (1) with n-butyllithium, sodium amide and potassium hydride yields the corresponding alkali metal N-mesityl-P,P-diphenylphosphoryl amides of lithium (2), sodium (3), and potassium (4). The lithium complex 2 forms a dimer with an eight-membered (Li-O-P-N)(2) ring. The sodium derivative 3 crystallizes as a dinuclear centrosymmetric complex with a central Na2O2 ring. The potassium congener 4 precipitates as a tetranuclear compound with an inner K4O4 heterocubane cage. In these complexes the phosphoryl amido ligands act as bidentate Lewis bases and form strained four-membered M-O-P-N rings. Due to this fact, the endocyclic M-O bonds of the M2O2 rings vary within a large range.
