The doubly stabilized P-ylide ligands Ph3P=C(CO2Me)C(=S)N(H)Ph (L1), Ph3P=C(CN)C(=S)N(H)Ph (L2), and Ph3P=C(CN)–[(E)-C(CO2Me)=CH(CO2Me)] (L3) have been prepared and fully characterized. The X-ray structures of L1 and L2 are reported. The reactivity of L1, L2, and L3 towards cationic PdII and PtII precursors with two vacant coordination sites has been studied. Adducts of general formula [M(CX)(Ln)]ClO4
双重稳定的 P-叶立德配体 Ph3P=C(CO2Me)C(=S)N(H)Ph (L1)、Ph3P=C(CN)C(=S)N(H)Ph (L2) 和 Ph3P= C(CN)–[(E)-C(CO2Me)=CH(CO2Me)] (L3) 已制备并充分表征。报告了 L1 和 L2 的 X 射线结构。已经研究了 L1、L2 和 L3 对具有两个空配位点的阳离子 PdII 和 PtII 前体的反应性。通式 [M(CX)(Ln)]ClO4、[M(CX)(Ln)2]ClO4 和 [M(μ-Ln)(CX)]2(ClO4)2 的加合物(CX = 辅助配体)获得了。叶立德 Ln 通过它们的杂原子(O、N、S)与金属中心配位,而在任何研究的情况下都没有观察到 Ln 的 C 键合。(© Wiley-VCH Verlag GmbH & Co.
