Purified LiAlH4 reacts with fluorinated alcs. HORF to give LiAl(ORF)4 (RF = -CH(CF3)2, 2a; -CMe(CF3)2, 2b; -C(CF3)3, 2c) in 77-90% yield. The crude Li aluminates LiAl(ORF)4 react metathetically with AgF to give the silver aluminates AgAl(ORF)4 (RF = -CH(CF ...
The reactions of the cluster complexes [Pt-3(mu -Co)(3)L-3], where L = PPh3 1a, PPh(2)Bz 1b and PCy3 1c, with activated mono-olefins have been studied under preparative and equilibrium conditions. At low temperature the olefins react quantitatively giving ...
Small addition of potassium to V/Ti-oxide catalyst (K:V=0.19), consisting of 3.7 monolayer VOx, increased activity and selectivity in partial oxidation of toluene. In order to elucidate the nature of vanadia species formed on the surface of V/Ti-oxide upon ...
The use of a tetrafunctional epoxy-based additive to modify the molecular structure of poly(ethylene terephthalate) (PET) was investigated with the aim of producing PET foams by an extrusion process. The molecular structure analysis and shear and elongatio ...
The influence of potassium on the formation of surface vanadia species on V/Ti oxide catalysts contg. from 0.2 to 5 monolayers of vanadia (K/V at. surface ratio ?1) has been investigated by temp. programmed redn. in hydrogen and by FT-Raman spectroscopy un ...
Since the first facile synthesis of Ru(H2O)(6)(2) was published at the beginning of the eighties, several Ru-II aqueous inorganic and organometallic complexes were described, showing the increasing interest in this kind of compound due to potential ...
The reaction rate, the catalyst potential, the catalyst work function and the voltammetric charge were in situ measured during a galvanostatic transient of ethylene combustion on an IrO2 catalyst at 380 Deg. The catalytic activity of an IrO2 catalyst could ...
The reaction of the cluster complexes [Pt-3(mu -CO)(3)(PR3)(3)] (PR3 = PPh3 1, PPh(2)Bz 2, PCy3 3 and P(i)pr(3) 4) with dialkyl acetylenedicarboxylate, R'O2CC drop CCO2R' (R= CH3 or Bu-t) have been examined under various conditions. At low temperature the ...
The effect of internal stresses on the cohesion and adhesion of a thin silicon oxide (SiOx) oxygen-barrier coating, evaporated on a poly(ethylene terephthalate) (PET) film substrate was studied. Internal stresses were generated during annealing in the temp ...
A device for the preventative photodynamic therapy of secondary cataract has been developed. Disturbance of the epithelial cells of the crystalline lens during the primary cataract surgery and/or their migration thereafter can frequently generate secondary ...
