The reaction between various bis(dialkylamino)chlorophosphines and N-isopropyl-substituted lithium amides afforded bis(α,α′-phosphino)imines in a ‘one-pot’ procedure. These compounds react with sulfur to generate intramolecularly hydrogen-bonded ylide derivatives. The molecular structure of (Pr2iN)2PCH2C(NBut)CH2P(NPri)2 has been determined by X-ray crystallography.
