Addition of Electron-Rich Aromatics to Azafullerenium Carbocation. A Stepwise Electrophilic Substitution Mechanism
(2003)(Matrix presented) The reaction between the C59N+ carbocation and the electron-rich aromatic compounds toluene and anisole has been mechanistically studied. The measured intermolecular kinetic isotope effects are consistent ...

Donor atom electrochemical contribution to redox potentials of square pyramidal vanadyl complexes
(2015)A simple donor atom additivity relationship has been used to calculate the donor atom electrochemical contribution (DEC) of the Oac (acetylacetonate-enolic oxygen), OPh (phenolic oxygen), SPh (mercaptophenol sulfur), Nam ...

Effects of the CePO 4 on the oxygen storage and release properties of CeO 2 and Ce 0.8Zr 0.2O 2 solid solution
(2004)In an attempt to gain fundamental information about the role of P on the chemical deactivation of a three-way catalyst (TWC), P was deliberatively incorporated in CeO 2 and Ce 0.8Zr 0.2O 2 solid solution. XRD, Raman, XPS, ...

NMR and theoretical investigations on the structures and dynamics of octahedral bis(chelate)dichloro VIII compounds isolated by an unusual reduction of non-oxo VIV species
(2003)Reaction of the non-oxo VIV species [VIVCl2(LOO)2] [LOO = acetylacetonate (acac-) or benzoylacetonate (bzac-)] with a chelate nitrogen-donor ligand LNN in acetonitrile leads to the reduction of VIV to VIII and the formation ...

The phenol steam reforming reaction over MgO-based supported Rh catalysts
(2004)The phenol steam reforming reaction toward H2 formation has been investigated in the 575-730°C range over MgO, CeO2, and ZrO 2 single metal oxides and various mixed metal oxides such as Mg-Ce-O, Mg-Zr-O, and Mg-Ce-Zr-O, ...

The reaction of 2-amino-N′-arylbenzamidines with tetracyanoethene reinvestigated: routes to imidazoles, quinazolines and quinolino[2′,3′:4,5]imidazo[1,2-c]quinazoline-8-carbonitrile
(2015)2-Amino-N′-phenylbenzamidine (1a) reacts with tetracyanoethene (TCNE) to give 2-[2-(2-aminophenyl)-5-imino-1-phenyl-1H-imidazol-4(5H)-ylidene]malononitrile (11a), 4-(phenylamino)quinazoline-2-carbonitrile (5a) and ...

Synthesis of a novel diene from a cyclobutane precursor: An entry to 2,9-disubstituted [2]diadamantanes
(2013)In the gas-phase thermolysis (350 C) of heptacyclic cyclobutane 2, n=1, (the [2+2] dimer of noradamantene) two isomeric dienes (the symmetric 5, n=1 and the asymmetric 6a) and the reduction product [2]diadamantane (7-H) ...
