  Mono- versus Bis-chelate Formation in Triazenide and Amidinate Complexes of Magnesium and Zinc

  摘要：

  Magnesium and zinc complexes of the monoanionic ligands N,N'-bis(2,6-di-isopropylphenyl)triazenide, L-1, N,N'-bis(2,6-di-isopropylphenyl)acetamidin ate, L-2, and N,N'-bis(2,6-di-isopropylphenyl)tert-butylamidinate, L-3, have been synthesized, but only L-3 possesses sufficient steric bulk to prevent bis-chelation. Hence, the reaction of (LH)-H-1 with excess ZnEt2 leads to the isolation of (L-1)(2)Zn, 1; (LH)-H-1 also reacts with BU2Mg in Et2O to afford (L-1)(2)Mg(Et2O), 2. Similar reactivity is observed for (LH)-H-2, leading to the formation of (L-2)(2)Zn, 3, and (L-2)(2)Mg, 4. The reaction of (LH)-H-2 with ZnR2 may also afford the tetranuclear aggregates {(L-2)Zn2R2}(2)O, 5 (R = Me) and 6 (R = Et). By contrast, the tert-butylamidinate ligand was found to exclusively promote mono-chelation, allowing (L-3)ZnCl(THF), 7, [(L-3)Zn(mu-Cl)](2), 8, (L-3)ZnN(SiMe3)(2), 9, (L-3)(MgPr)-Pr-i(Et2O), 10, and (L-3)(MgPr)-Pr-i(THF), 11, to be isolated. X-ray crystallographic analyses of 1, 2, 3, 4, 5, 6, 8, and 10 indicate that the capacity of L-3 to resist bis-chelation is due to greater occupation of the metal coordination sphere by the N-aryl substituents.

  摘要：

  首次以 2,6-二异丙基苯胺和酸氯化物为原料，通过相应的亚胺酰氯制备出了 N,Nâ²-双（2,6-二异丙基苯基）-4-甲苯胺、-4-甲脒和-乙脒。这三种脒的晶体结构均已确定，表明在固态下，第一种脒是 Z-反式和 E-syn 同分异构体的无序混合物，第二种脒是 Z-反式，第三种脒是 E-反式。尽管存在这些差异，但这三种化合物都与 Mo(CO)3 形成了相同的配位复合物，其中配体呈 Z-anti 几何结构，金属与 2,6-二异丙基苯基亚氨基环配位，氨基 NâH 单元朝向金属。这种配位模式通过测定甲脒和甲脒与 Mo(CO)3 的单晶 X 射线结构得到了证实。仅就甲脒而言，首先形成了一个可分离的中间体，其中的中性脒以单配位方式与 Mo(CO)5 单元配位。该复合物的晶体结构显示，配体呈 E-anti 几何结构，亚氨基氮与 Mo 配位，d(MoâN)Â =Â 2.352(2) Ã。这两种结构密切相关，最初的 Mo(CO)5 N 配位使金属转化为热力学上更稳定的 Ï 配位 Mo(CO)3 复合物。这些超脒配体的高立体体积体现在它们中的任何一种都无法形成通常使用体积较小的普通脒制备的金属键 Mo2（脒基）4 复合物。

  The tin(II) coordination chemistry of two monoanionic N,N′-bis(2,6-diisopropylphenyl)alkylamidinate ligands is described. Complexation studies with the acetamidinate, [MeC(NAr)2]−, (Ar = 2,6-iPr2C6H3) are complicated by the side formation of the bis(amidinate) tin(II) compound, [MeC(NAr)2]2Sn, 1. By contrast, the bulkier tert-butylamidinate, [tBuC(NAr)2]−, allows tin(II) mono-halide, -alkoxide and -amide complexes to be isolated cleanly in high yields. Thus, the reaction of [tBuC(NAr)2]H with nBuLi and subsequent treatment with SnCl2 generates [tBuC(NAr)2]SnCl, 2, in ca. 70% yield. Reactions of 2 with LiOiPr, LiNMe2 and LiNTMS2 afford [tBuC(NAr)2]Sn(OiPr), 3, [tBuC(NAr)2]Sn(NMe2), 4, and [tBuC(NAr)2]Sn(NTMS2), 5, respectively. The molecular structures of complexes 1–4 are reported. Complexes 3, 4 and 5 have been investigated as initiators for the ring-opening polymerisation of rac-lactide: 3 and 4 display characteristics of well-controlled polymerisation initiators, but high molecular weight polymer is observed with 5 due to inefficient initiation, a consequence of the steric bulk of the NTMS2 unit. Polymerisations with 3 and 4 are faster than for the corresponding β-diketiminate tin(II) complexes, consistent with the more open nature of the tin(II) coordination sphere.

  描述了两种单负离子N,N′-双(2,6-二异丙基苯基)烷基氨基酸配体的锡(II)配位化学。与乙酰氨酸盐[MeC(NAr)2]−（Ar = 2,6-iPr2C6H3）的络合研究因副产物的形成而变得复杂，该副产物为双(氨基酸)锡(II)化合物[MeC(NAr)2]2Sn，1。相反，体积更大的叔丁基氨基酸盐[tBuC(NAr)2]−则能够以高产率纯化锡(II)单卤化物、-醇盐和-酰胺配合物。因此，[tBuC(NAr)2]H与nBuLi反应并随后用SnCl2处理生成[tBuC(NAr)2]SnCl，2，产率约为70%。与LiOiPr、LiNMe2和LiNTMS2的反应分别得到[tBuC(NAr)2]Sn(OiPr)，3，[tBuC(NAr)2]Sn(NMe2)，4，以及[tBuC(NAr)2]Sn(NTMS2)，5。报告了配合物1-4的分子结构。配合物3、4和5被研究作为开环聚合的引发剂：3和4表现出良好控制的聚合引发剂特性，但由于NTMS2单元的空间庇护效应，5显示出聚合效率低下，导致高分子量聚合物的生成。3和4的聚合速度快于相应的β-二酮氮基锡(II)配合物，这与锡(II)配位球更开放的性质相一致。

  A halogenated aromatic monomer-metal complex useful for preparing a polymer for electronic devices such as a light-emitting diode (LED) device is described. The aromatic monomer-metal complex is designed to include a linking group that disrupts conjugation, thereby advantageously reducing or preventing electron delocalization between the aromatic monomer fragment and the metal complex fragment. Disruption of conjugation is often desirable to preserve the phosphorescent emission properties of the metal complex in a polymer formed from the aromatic monomer-metal complex. The resultant conjugated electroluminescent polymer has precisely controlled metal complexation and electronic properties that are substantially or completely independent of those of the polymer backbone.

  The reaction of mesitylamine (2,4,6-Me3C6H2NH2) with two equivalents of imidoylchloride, ArN=C(Cl)Me (Ar=2,4,6-Me3C6H2 or 2,6-iPr(2)C(6)H(3)) in the presence of Et3N yields neutral [N,N'] chelating ligands, [2,4,6-Me3C6H2NC(Me)N(2,4,6-Me3C6H2)}(2)] (L-1) and a pair of ligand isomers; symmetrical [2,4,6-Me3C6H2NC(Me)N(2,6-iPr(2)C(6)H(3))}(2)] (L-2a) & unsymmetrical [2,6-iPr(2)C(6)H(3)NC(Me)N(2,6-iPr(2)C(6)H(3))C(Me) N(2,4,6-Me3C6H2)] (L-2b). An exclusive synthesis of the unsymmetrical isomer L(2)b has also been optimized by the reaction of a preformed amidine (2,6-iPr(2)C(6)H(3))NHC(Me)=N(2,6-iPr(2)C(6)H(3))} with the mesityl imidoylchloride. The three ligands have been thoroughly characterized by spectroscopic and X-ray diffraction methods (for L-2a and L-2b). The reaction of equimolar quantities of L-1 with CoCl2 center dot 6H(2)O, NiBr2 center dot xH(2)O, Cu(NO3)(2)center dot 3H(2)O yields the corresponding mononuclear complexes, L-1 center dot CoCl2 (I), L-1 center dot NiBr2 (2) and L-1 center dot Cu(NO3)(2) (3). Similarly, reaction of unsymmetrical ligand isomer L-2b with CoCl2 center dot 6H(2)O, NiBr2 center dot xH(2)O, or CuCl2 affords the complexes L-2b center dot CoCl2 (4), L-2b center dot NiBr2 (5) and L-2b center dot CuCl2 (6), respectively. The solid state structures of complexes 1-6 have been investigated by single crystal X-ray structural analysis. (C) 2015 Elsevier Ltd. All rights reserved.
