摘要：

Unprecedented N-phosphino-beta -diimine ligands 4 and 5 have been prepared from a facile one-pot synthesis using malonodinitrile, CH2(CN)(2), the Schwartz reagent [Cp2Zr(H)Cl](n) (1), and the corresponding chlorophosphines R2PCl 2 and 3. An alkyl aluminum complex and the corresponding bidentate lithium salt ligand have been isolated. We showed that the reactivity of the N-phosphino-beta -diimine compound 4 and that of the corresponding N-thiophosphino-beta -diimine derivative 6 with HCl are completely different. The chemistry reported suggests unique and interesting chelating behavior which may differ from that of existing beta -diimine ligands.
