revealed that both complexes feature cis-configuration of the P- and O-donor atoms in solution and in the solid state. Reaction of 7a, b with acetylacetonato or alkoxide complexes [MO2(acac)2] (M = Mo, W), [VO(acac)2], [Ti(μ-O)(acac)2}2], or Ti(OiPr)4 gave good to excellent yields of early-late heterometallic complexes [MOn(μ-L)2M′] (MOn = MoO2, WO2, VO; 8a, b–10a, b) or [Ti(RO-1κO)2(μ-L-1κ2O, O'-2κ2P, O)2Pd]
儿茶酚膦 2 (H2L) 与 [M'Cl2(cod)](cod = 1, 5-环辛二烯,M' = Pd, Pt)的碱辅助反应产生螯合物 [M'(HL)2] (7a, b)。光谱和单晶 X 射线衍射研究表明,这两种配合物在溶液和固态中都具有 P 和 O 供体原子的顺式构型。7a、b 与乙酰丙酮或醇盐配合物 [MO2(acac)2] (M = Mo, W)、[VO(acac)2]、[Ti(μ-O)(acac)2}2]、或Ti(OiPr)4 对早晚异金属配合物 [MOn(μ-L)2M'] (MOn = MoO2, WO2, VO; 8a, b–10a, b) 或 [Ti(RO-1κO )2(μ-L-1κ2O, O'-2κ2P, O)2Pd] (R = Me, iPr; 11a, b),这是通过其他合成途径无法获得的。光谱和单晶 X 射线衍射研究表明,早期金属中心位于 8a、b、图 9b 和图 11b
