Publikováno v: Advanced Synthesis & Catalysis. 356:951-960

Palladium nanoparticles dispersed in ammonium salts of hyperbranched polystyrenes are adhesively immobilized on the surface of cotton or filter papers by simply heating with dicarboxylic acids or halide anions. The resulting Pd@cotton and Pd@filter p

Nickel(II), Palladium(II), and Platinum(II) η3-Allyl Complexes Bearing a Bidentate Titanium(IV) Phosphinoamide Ligand: A Ti←M2 Dative Bond Enhances the Electrophilicity of the π-Allyl Moiety

Autor: Hideo Nagashima, Hironori Tsutsumi, Kazunari Yoshizawa, Yoshihito Shiota, Yusuke Sunada

Publikováno v: Organometallics. 28:1988-1991

Three Ti−M2 (M2 = Ni, Pd, Pt) heterobimetallic complexes, [(η3-methallyl)M2(Ph2PNtBu)2TiCl2](OTf), were synthesized in which a TiIV←M2 interaction was suggested by crystallography and DFT calculati...

Publikováno v: Materials Research Express. 3:055201

Relaxation dynamics of ion damage in fused quartz is investigated by our newly developed pump–probe technique combining energetic ions (pump) with slow positrons (probe). This method enables determination of time-resolved positron lifetime. We stud

Publikováno v: Chemical communications (Cambridge, England). 48(86)

Development of a new preparative procedure for hyperbranched polystyrene having Cl end groups (HPS-Cl) enables to prepare HPS-NR(3)(+)Cl(-), for which the hydrophobicity/hydrophilicity is tunable by the R groups. The resulting ammonium salts behave a
