The first example of palladium catalysed non-perfectly alternating copolymerisation of ethene and carbon monoxideElectronic supplementary information (ESI) available: ligand syntheses and NMR analyses of copolymers. See http://www.rsc.org/suppdata/cc/b1/b111629k/
Linear copolymers of ethylene and acrylonitrile were prepared using palladium complexes bearing phosphine-sulfonate bidentate ligands. Acrylonitrile units located in the linear polyethylene backbones were detected for the first time by 13C NMR spectroscopy. Catalyst systems employing isolated palladium complexes such as 3 showed much higher activity for the copolymerization than the in situ generation

Reaction of diarylphosphinobenzene-2-sulfonic acids with tertially amines, followed by addition of [PdMeCl(cod)], provided anionic methylpalladium(II) complexes with bidentate phosphineâsulfonate ligands, which show high activity for copolymerization of ethylene with methyl acrylate.
of various neutral phosphine containing copper(I) complexes exhibiting phosphorescence and TADF are easily achieved by solvent modification restricting intramolecular rotation or by modifying the L–X phosphine-sulfonate chelate. This concept is not limited to solvents as the addition of metallicsalts also led to the formation of original well-defined photoluminescent K2CuLX3 and KCuL2X2 cuprate complexes
通过限制分子内旋转的溶剂修饰或通过修饰L–X膦磺酸盐螯合物,可以轻松实现对各种具有磷光和TADF的中性磷化氢铜(I)配合物的调节。该概念不限于溶剂,因为添加金属盐还导致形成原始的明确定义的光致发光K 2 CuLX 3和KCuL 2 X 2铜酸盐配合物。

cyclometalated Ir (III) complexes (Ir1‐Ir4) containing different phosphine‐sulfonate ligands are reported. Most of these complexes showed good activity against A549 cancer cell lines and the human HeLa cervical cell lines. Spectroscopic properties study displays that all four complexes show rich fluorescence with emission maxima in the range of 474–510 nm. Fluorescence property of these complexes provides a

sulfonate nickel complexes [(o-Ar2PC6H4SO3)Ni(allyl)] (Ar = Ph, o-MeOC6H4) are prepared and used as catalysts for ethylene polymerization. The products were low molecular weight polyethylenes possessing only methyl branches. The activity for ethylene polymerization with the phenyl-substituted complex was comparable to that of o-methoxyphenyl-substituted complex in the absence of activator. Comparison with
制备膦磺酸盐镍配合物[(o -Ar 2 PC 6 H 4 SO 3)Ni(烯丙基)](Ar = Ph,o- MeOC 6 H 4),并将其用作乙烯聚合的催化剂。产物是仅具有甲基支链的低分子量聚乙烯。在没有活化剂的情况下,用苯基取代的配合物进行乙烯聚合的活性与邻甲氧基苯基取代的配合物的活性相当。与相应的烯丙基钯配合物的比较表明,与钯催化剂相比,镍催化剂生产的聚乙烯分子量更低,支链更多。
