摘要：

A series of ruthenium complexes with the orthometallated ligand [2,6-(Ph2PCH2)(2)C6H3](-) (PCP) was synthesized. Reaction of RuCl2(PPh3)(3) with 1,3-(Ph2PCH2)(2)C6H4 produced the coordinatively unsaturated complex RuCl(PPh3)(PCP), which was characterized by X-ray crystallography. Treatment of RuCl(PPh3)(PCP) with 4-phenylpyridine (pyph) yielded RuCl(pyph)(PPh3)(PCP). Treatment of RuCl(PPh3)(PCP) with PMe3 and CO generated RuCl(PMe3)(2)(PCP) and RuCl(CO)(2)(PCP) respectively. Reactions of RuCl(PPh3)(PCP) with NaH in THF and NaBH4 in methanol gave RuH(PPh3)(PCP) and RuH(CO)(PPh3)(PCP) respectively. The hydride complex RuH(PMe3),(PCP) was prepared by the reaction of RuCl(PMe3),(PCP) with NaBH4.
