  CSi bond cleavage of trihalomethyltrimethylsilane by alkoxo- and aryloxogold or -copper complexes

  摘要：

  The C-Si bond cleavage of trihalomethyltrimethylsilane Me3SiCX3 (X= F, Cl) proceeds smoothly by alkoxo- and aryloxogold(I or III) or -copper(I) complexes Au(OR)L (OR = OCH(CF3)(2), OPh), L = PCy3, PPh3, PMe2Ph, PMe3), cis-AuMe2(OPh)L (L = PMePh2, PEt3, PMe2Ph, PMe3), Cu(OR)(PPh3)(3) (OR = OCH(CF3)(2), OPh) to give trihalomethylgold or -copper complexes Au(CX3)L, cis-AuMe2(CF3)L, or Cu(CF3)L-3 with liberation of the corresponding silyl ether Me3SiOR.

  Mono- and dinuclear alkoxide copper complexes with PPh3 ligands

  摘要：

  Methylcopper complex, CuMe(PPh3)2(Et2O)0.5 (1), reacts with HOCH(CF3)2 to give Cu(OCH(CF3)2)(PPh3)3 (2a). Similar reactions of 1 with HOCHPh2 give Cu(OCHPh2XPPh3)3 (3a) or Cu(OCHPh2)(PPh3)2 (3b) depending on the reaction conditions. Reaction of 1 and phenol with addition of PPh3 gives Cu(OPhXPPh3)3 (4a). The H-1 NMR spectra and results of elemental analyses of 2a, 3a, 3b, and 4a agree well with the proposed formula. Complex 2a crystallizes in the orthorhombic space group Pn2(1) a, with a = 18.804(2) angstrom, b = 19.655(4) angstrom c = 13.175(3) angstrom, Z = 4, and V = 4869 angstrom3. The Cu center is in pseudotetrahedral coordination with the Cu-O distance of 2.087(6) angstrom. Phenoxide copper complex, Cu(OPh)(PPh3)2 (4b), which is prepared from the already reported reaction of 1 with phenol, crystallizes in the monoclinic space group P2, with a = 13.955(3) angstrom, b = 17.610(3) angstrom, c = 13.961(3) angstrom, beta = 90.06(2), Z = 2, and V = 3430 angstrom3. The molecule has a dinuclear structure in which two pseudotetrahedral Cu centers are bridged by two mu2-phenoxide ligands. Complex 3a reacts with HOCH(CF3)2 to give 2a, while reactions of the fluoro alcohol with 3b give 2a or Cu(OCH(CF3)2)(PPh3)2 (2b) depending on the conditions. Reaction of HOCHPh2 with 2a does not cause the alkoxide ligand exchange. Complex 2a reacts with phenol and with phenyl acetate to give 4b in high yields, while 4b does not undergo exchange of the phenoxide ligand by HOCH(CF3)2. Reaction of 3a with 1,4-diethynylbenzene gives a copper complex formulated as (Ph3P)Cu(C=CC6H4C=C)Cu(PPh3) (5). The PEt3 coordinated complex (Et3P)Cu(C=CC6H4C=C)Cu(PEt3) (6) is prepared by reaction of PEt3 with 5.

  and NiII, CuI,II, ZnII, and HgII reactants were investigated by synthesis and X-ray crystal structures of some 24 complexes. This work was stimulated by recent crystallographic structures of the A-cluster of carbon monoxide dehydrogenase/acetylcoenzyme A synthase. This bridged biological assembly has the minimal formulation [Fe4S4]-(micro2-SCys)-[M((micro2-SCys)2Gly)Ni] with M = NiII, CuI, and ZnII

  通过合成和约24种配合物的X射线晶体结构研究了三种顺式NiII-S2N2配合物与NiII，CuI，II，ZnII和HgII反应物之间的硫桥联反应。一氧化碳脱氢酶/乙酰辅酶A合酶的A簇的最新晶体学结构刺激了这项工作。这种桥接的生物组装体具有最小的[Fe4S4]-（micro2-SCys）-[M（（micro2-SCys）2Gly）Ni]构型，在铁的远端和近端分别具有M = NiII，CuI和ZnII -硫簇。通过配合物[NiII（LH-S2N2）] 2-和[NiII（LR-S2N2）]与5-5-5螯合环的反应来寻找由远端镍位点表示支持的桥。反应产物将桥Ni-（micro2-S）1,2-M包含在各种分子结构中，一些具有桥原子以前未知的连通性。最常遇到的桥单元是涉及给定配合物的两个硫​​原子的非平面菱形Ni（2-S）2M。M = NiII的那些在生物学上是相关的，因为在近端的催化金属是镍。制备了复合物[Ni（L-655）]
