Why are (NN2)Ni pincer complexes active for alkyl-alkyl coupling: ß-H elimination is kinetically accessible but thermodynamically uphill

Rosario Scopelliti, Xile Hu, Oleg Vechorkin, Jan Breitenfeld

Isomerization and olefin exchange experiments show that β-H elimination is kinetically viable but thermodynamically unfavorable in [(MeNN2)Ni-alkyl] complexes. The intermediacy of Ni-hydride species was corroborated by a trapping experiment. The alkyl comp ...

A modeling framework for product development process considering its characteristics

Product development (PD) processes are complex and unstructured compared to business or manufacturing processes, as they have iterative, evolutionary, uncertain, and cooperative features. In order to effectively manage and control a complex PD process, app ...

Electrochemical modification of the catalytic activity of TiO2/YSZ supported rhodium films

Christos Comninellis, György Foti

The electrochemical activation of ethylene oxidation was studied over rhodium catalysts of different thickness (40, 100 and 160 nm) sputtered on top of a thin layer of TiO2 deposited on YSZ. The strong relationship between catalytic activity and oxidation ...

Positively Charged GdIII Cryptates: Slow, Associative Water Exchange

André Merbach, Lothar Helm, Eva Jakab Toth

A combined variable-temp. and multiple field 17O NMR, EPR and NMRD study was performed for the 1st time on Gd(III) complexes of cryptand ligands, L1 and L2, where L1 contains three 2,2'-bipyridine units ([bpy.bpy.bpy]) and L2 is the disubstituted Me ester ...

Development of Organometallic Ruthenium-Arene Anticancer Drugs That Resist Hydrolysis

Paul Joseph Dyson, Wee Han Ang, Claudine Scolaro, Elisa Daldini

With a view to develop drugs that could resist hydrolysis in aq. media,organometallic arene-capped ruthenium(II) 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (RAPTA) complexes bearing chelating carboxylate ligands have been prepd. and studied. The new com ...

Hydrogenation reactions in ionic liquids: Finding solutions for tomorrow's world

Paul Joseph Dyson, Dongbin Zhao

Ionic liquids are excellent solvents for conducting biphasic hydrogenation reactions offering many advantages over both related homogeneous processes and biphasic reactions in other alternative solvents. The relevant physicochemical properties of ionic liq ...

Novel reactive perstraction system applied to the hydrolysis of penicillin G

Urs von Stockar, Ian William Marison

The activity of penicillin acylase has been studied in aq. and org. solvents, as free enzyme as well as immobilized within the membrane of liq.-core capsules. The activity of the enzyme is inhibited by the accumulation of the products of the hydrolysis rea ...

A phenomenological model for macroscopic deactivation of surface processes

Christos Comninellis, Hannes Bleuler, Rolf Wüthrich

There is a wide class of electrochemical systems which present a sudden transition from a high to a low reaction rate region in function of an external parameter. This sudden transition is accompanied by the growth of a surface structure responsible for de ...

Iron mobilization in mineral dust: Can anthropogenic SO2 emissions affect ocean productivity?

Athanasios Nenes

For Fe contained in long-range transported acolian dust to act as a micronutrient for oceanic phytoplankton it must be first dissolved or mobilized. We propose that Femobilization can occur in mineral dust from East Asia by the incorporation of SO2 into th ...
