Popis: Metallation of the NH-functional amino(imino)phosphanes Mes*NPNHR (R = CPh3, Ad, tBu) 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.
