Monomer and Dimer 1,3‐Diaza‐2‐phosphaallyllithium Complexes: Structures and Ambident Reactivity * Metallation of the NH‐functional amino(imino)phosphanes Mes * NPNHR (R = CPh 3 , Ad, t Bu) 1a–c yields the 1,3‐diaza‐2‐phosphaallyllithium compounds 2a–c . The crystal structure shows an ether‐stabilized monomer of 2a and a solvent‐free dimer with an eight‐membered ring in the case of 2b, c . The reaction of 2b with chlorodiphenylphosphane yields, dependent on the reaction conditions, (phosphanylamino)iminophosphane 3 or bis(imino)phosphanylphosphorane 4 . The structural and reactivity is discussed on the basis of ab initio calculations.
