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.

The reaction of PSCl3 with Pri2NH at 60 °C affords the disubstitution product (Pri2N)2P(S)Cl without first forming the monosubstitution product Pri2NP(S)Cl2; a PIII compound (possibly PCl3) generated in situ seems to be a crucial intermediate.
