Concerted Diels-Alder reaction between anthracene and C60
(2001)
The Diels-Alder reaction of anthracene with C60 has been investigated experimentally by using secondary isotope effects. The inverse α-secondary isotope effect in conjunction with the unity value of the β-secondary isotope ...
Ene Reaction of Arylallyl Alkenes with C60. A Mechanistic Approach
(1999)
(Matrix Presented) The ene reaction of arylallyl alkenes with C60 occurs either by a concerted mechanism or by the reversible formation of a charged or a dipolar intermediate, followed by the C-H(D) breakage in a rate-limiting ...
A magnetostructural investigation of an abrupt spin transition for 1-phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl
(2014)
1-Phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl is the first example of a hydrazyl radical that shows a reversible sharp spin transition fully completed within 5(1) K. The nominally first-order transition ...
Structural, magnetic, and computational correlations of some imidazolo-fused 1,2,4-benzotriazinyl radicals
(2014)
1,3,7,8-Tetraphenyl-4,8-dihydro-1H-imidazolo[4,5g][1,2,4]benzotriazin-4-yl (5), 8-(4-bromophenyl)-1,3,7-triphenyl-4,8-dihydro-1H-imidazolo[4,5g][1,2,4] benzotriazin-4-yl (6), and 8-(4-methoxyphenyl)-1,3,7-triphenyl-4,8-dihydro-1H- ...
The suppression of columnar π-stacking in 3-adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl
(2016)
3-Adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl(4) crystallizes as chains of radicals where the spin bearing benzotriazinyl moieties are isolated from each other. Magnetic susceptibility studies in the 5-300 K ...
Low-temperature conversion of phenol into CO, CO 2 and H 2 by steam reforming over La-containing supported Rh catalysts
(2012)
The steam reforming of phenol in the low-temperature range of 350-550°C was studied over 0.5wt% Rh supported on Ce 0.15Zr 0.85O 2, Zr 0.93La 0.07O 2, and Ce 0.13Zr 0.83La 0.04O 2 mixed metal oxides. The reforming specific ...
The remarkable effect of oxygen on the N2 selectivity of water catalytic denitrification by hydrogen
(2007)
The selective catalytic reduction of nitrates (NO3-) in pure water toward N2 formation by the use of gaseous H2 and in the presence of O2 (air) at 1 atm total pressure and 25°C has been investigated over Pd-Cu supported ...
Reactions of 1,2,3-dithiazoles with halogenated malononitriles
(2002)
Dibromomalononitrile 3a reacts with 4-chloro-1,2,3-dithiazole-5-thione 9 and monobromomalononitrile 3c reacts with 4,5-dichloro-1,2,3-dithiazolium chloride 4 (Appel salt) to give 4-chloro-5H-1,2,3-dithiazole-5-ylidenemalononitrile ...
Reactivation of an aged commercial three-way catalyst by oxalic and citric acid washing
(2006)
The efficiency of dilute oxalic and citric acid solutions on improving the oxygen storage capacity (OSC) and catalytic activity of a severely aged (83 000 km) commercial three-way catalyst (TWC) has been investigated. ...
Reactivation of severely aged commercial three-way catalysts by washing with weak EDTA and oxalic acid solutions
(2007)
Ethylene diamine tetraacetic acid (EDTA) which is a well-known reagent for its metal extraction efficiency was studied for the first time towards the improvement of the catalytic activity and oxygen storage and release ...
