Reaction of these proligands HLn (n = 1–5) with [WO2Cl2(DME)] (DME = 1,2-dimethoxyethane) in the presence of triethylamine leads to the formation of cis-dioxotungsten(VI) complexes [WO2(Ln)Cl] (n = 1–5). Treatment of the chloro derivatives [WO2(Ln)Cl] (n = 1, 5) with the Grignard reagents RMgX (R = CH2SiMe3, C6H4tBu-4; X = Cl, Br) resulted in ligand substitution reaction and the formation of the first

(PDT) to human cervical cancer (HeLa) cells. Although all of the complexes were toxic in the dark (IC50 ≈ 10 µm), we observed enormous enhancement (about 10 fold) in the cytotoxicity of the complexes in visible light (400–700 nm, 10 J cm–2), resulting in IC50 ≈ 1.0 µm. Intracellular reactive oxygen species (ROS) generated in the HeLa cells during photoactivation of the complexes was examined by 2′,7′

phthalonitrile derivatives have been prepared from tridentate amine thiol reactants obtained by reducing directly two different benzothiazolines. Novel metal free phthalocyanines and divalent metal phthalocyanines carrying four tridentate NNS substituents in addition to four chloro groups on peripheral positions have been synthesized from the corresponding phthalonitrile derivatives in the presence of a suitable
已经通过直接还原两种不同的苯并噻唑啉获得的三齿胺硫醇反应物制备了两种新的4,5-二取代的邻苯二甲腈衍生物。在合适的无水金属盐[Zn(CH 3 CO 2)2或NiCl的存在下,由相应的邻苯二甲腈衍生物合成了新型的无金属酞菁和二价金属酞菁,它们在周边位置还带有四个三齿的NNS取代基。2 ]或2-(二甲基氨基)乙醇。由一种邻苯二甲腈衍生物与无水(reaction)反应合成了在大多数有机溶剂中高度可溶的III(Ⅲ)双(酞菁)络合物。III)在1-己醇中的1,8-二氮杂双环[5.4.0]十一碳-7-烯(dbu)存在下的乙酸盐。新合成的化合物已通过元素分析,IR,1 H,13 C NMR,MS,UV / VIS,ESR和原子吸收光谱法进行了表征。已经进行了新型化合物的循环伏安测量。

The zinccomplex chemistry of the tridentate thiol ligand N- (2-mercaptophenyl)(2-picolyl)amine (MPPAH) differs considerably from that of the aliphatic analogue N-(2-mercaptoethyl)(2-picolyl)amine reported previously. This is due to the lower basicity and hence bridging tendency of its aromatic thiolate function. With zinc salts of oxo anions the 1:1 complexes (MPPA)ZnX (1a–c: X = ONO2, OAc, OBz) are
三齿硫醇配体N-(2-巯基苯基)(2-吡啶甲基)胺(MPPAH)的锌络合物化学与先前报道的脂族类似物N-(2-巯基乙基)(2-吡啶甲基)胺的锌络合物有很大不同。这是由于较低的碱性,因此其芳族硫醇盐官能团的桥接趋势。用含氧阴离子的锌盐形成1:1络合物(MPPA)ZnX(1a–c:X = ONO 2,OAc,OBz),根据光谱数据,它们是单体,而卤化物(MPPA)ZnBr(2)似乎是具有聚合性。在没有配位阴离子的情况下,单体2:1配合物(MPPA)2Zn(3)结果,根据晶体结构确定,其包含一个MPPA配体以三齿形式配位的四面体锌,而另一个仅是单齿且与硫结合。对于由ZnEt 2,MPPAH和三苯基甲硫醇形成的1:1:1配合物(MPPA)Zn(STrt)(4),可以推论出类似的N 2 S 2配位。

The crystalstructure of Mo2O5[SC6H4NHCH2C5H4N]2(C3N7NO)3 is reported and seen to consist of a single oxo-bridged species with each Mo atom bonded to cis dioxo groups and the nitrogen atoms and thiolate group of the tridentate ligand. 95Mo NMR spectra of this and three related complexes are presented and attempts made to interpret them in terms of their crystalstructures.
