  tris-β-diketiminate ytterbium complexes with the general formula [YbL 3 ] L = [N(C 6 H 5 )C(Me)] 2 CH - , L H (1); [N(4-MeC 6 H 4 )C(Me)] 2 CH - , L 4-Me (2), and [N(2-MeC 6 H 4 )-C(Me)] 2 CH - , L 2-Me (3)) were synthesized and structurally characterized. All complexes have longer Yb-N bond lengths than other YbL-containing derivatives, and complex 3 has the longest average Yb-N bond length. A comparative study

  一系列具有通式 [YbL 3 ] L = [N(C 6 H 5 )C(Me)] 2 CH - , LH (1) 的三-β-二酮亚胺镱配合物；[N(4-MeC 6 H 4 )C(Me)] 2 CH - , L 4-Me (2), 和 [N(2-MeC 6 H 4 )-C(Me)] 2 CH - , L 2 -Me (3)) 被合成和结构表征。所有配合物的 Yb-N 键长都比其他含 YbL 的衍生物长，配合物 3 的平均 Yb-N 键长最长。对配合物1-3反应性的比较研究表明，配合物3是ε-己内酯和L-丙交酯聚合以及胺加成碳二亚胺的高活性催化剂，而配合物1和2都是在相同条件下几乎不活动。活性序列与Yb-N键的距离一致，
• Facile Dehydrogenation of Ethers and Alkanes with a <i>β</i>-Diiminate Pt Fragment

  Me4Pt2(μ-SMe2)2 in diethyl ether results in dehydrogenation of the solvent to form the Pt(II) olefin hydride complex (nacnac)Pt(ethyl vinyl ether)(H). Activation of ethers is kinetically favored over activation of alkanes. The KIE for ether activation (2.2) is significantly lower than that for pentane activation (3.8), indicating that initial coordination through oxygen is the likely pathway for ether activation

  中性 β-烯胺亚胺配体 (nacnacH) 和 Me4Pt2(μ-SMe2)2 在乙醚中的反应导致溶剂脱氢形成 Pt(II) 烯烃氢化物络合物 (nacnac)Pt(乙基乙烯基醚)(H) . 醚的活化在动力学上优于烷烃的活化。醚活化 (2.2) 的 KIE 显着低于戊烷活化 (3.8)，表明最初通过氧气配位是醚活化的可能途径。二乙醚和 THF 的边际催化转移脱氢是通过在 50 °C 下加热（nacnac）Pt（新己烯）（H）几天来实现的，过量的新己烯作为氢受体。

  Three new beta-diketiminatolead(II) chlorides have been synthesised, including [(BDIDmp)PbCl], [(BDIIPP)-PbCl] and [(BDIph)PbCl] (BDIDMP = [N(2,6-Me2C6H3)C(Me)}(2)CH], BDIIPP = [N(4-(PrC6H4C)-Pr-i(Me)}(2)CH] and BDIPh = [N(C6H5)C(Me)}(2)CH]). Addition of sodium or potassium-alkoxide salts to [(BDIIPP)PbCl] or [(BDIPh)PbCl] resulted in the unexpected formation of bis(beta-diketiminato)lead(II) complexes, [(BDIIPP)(2)Pb] and [(BDIPh)(2)Pb], whereas addition to [(BDIDMP)PbCl] led to the expected lead alkoxo complex, [(BDIDMP)-(PbOBu)-Bu-t] The lead(II) triflate complex, [(BDIDMP)PbOTf], was synthesised by treatment of [(BDIDMP)PbCl] with AgOTf.

  A series of ruthenium-benzene complexes with beta-diketiminate ligands modified with electron-withdrawing groups were prepared and characterized by NMR spectroscopy, Mass spectrometry, and single-crystal X-ray diffraction. The complexes are stable in air and Undergo controlled hydrolysis in water. The complexes were evaluated for anticancer activity in vitro, and two of them proved to be highly cytotoxic, comparable or even superior to cisplatin. This work shows the potential utility of the beta-diketiminate ligand in the rational design of new anticancer metal-containing drugs. A related complex with a eta(6)-C6H5CF3 ligand was prepared and found to undergo a nucleophilic addition reaction at the coordinated arene ring to afford a Substituted eta(5)-cyclohexadienyl derivative.
• Synthesis of lanthanide chlorides supported by β-diketiminate ligands and molecular structures of L1SmCl2(THF)2 and L2SmCl2(THF)2 [L1=PhNC(Me)CHC(Me)NPh; L2=p-ClPhNC(Me)CHC(Me)NPh(2,6-Pri2)]

  The beta-diketiminate lithium salts [(LLi)-Li-1, L-1 = PhNC(Me)CHC(Me)NPh; (LLi)-Li-2, L-2 = p-ClPhNC(Me)CHC(Me)NPh(2,6-Pr-2(i))] reacted with anhydrous LnCl(3) (Ln = Sm, Yb) in 1: 1 molar ratio in THF to afford the new heteroleptic lanthanide complexes L(1)LnCl(2)(THF)(2) (Ln = Sm (1), Yb (2)) and L(2)LnCl(2)(THF)(2) (Ln = Sm (3), Yb (4)) in high yields. The substituents on the arene ring have significant effect on the solubility of these complexes. Crystal structure analysis revealed that complexes I and 3 are both monomeric, in which the samarium atom is coordinated by two nitrogen atoms of the beta-diketiminate ligand, two chloro and two THF ligands in distorted octahedral environment.
