摘要

Unprecedented N-phosphino-#beta#-diimine ligands 4 and 5 have been prepared from a facile one-pot synthesis using malonodinitrile, CH_2(CN)_2, the Schwartz reagent [Cp_2Zr(H)Cl]_n (1), and the corresponding chlorophosphines R_2PCl 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#-diiminie 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.
