The new amines, HN(CH2CH2PR2)2 (R = Me, Et), have been prepared by the nucleophilic substitution of halide in HN(CH2CH2Cl)2·HCl or the free amine by the corresponding dialkylphosphido anions. The new amines are readily deprotonated by the action of alkyllithium reagents. Action of the amido anion, −N(CH2CH2PMe2)2, on VCl3·3THF leads to the new ternary amide Cl2VN(CH2CH2PMe2)2, from which a new class
