8-[2-Chloro-5-(trifluoromethyl)phenyl]-4H-[1,2,4]oxadiazolo-[3,4-c][1,4]benzoxazin-1-one
(2011)
8-Bromo-4H-[1,2,4]oxadiazolo[3,4-c][1,4]benzoxazin-1-one 1 (NS2028) reacts with [2-chloro-5-(trifluoromethyl)phenyl]boronic acid 2 (2 equiv), Pd(OAc)2 (10 mol%) and KOAc (4 equiv) in acetonitrile heated to ca. 110 °C (sealed ...
Synthesis of sulfur containing analogues of the soluble guanylate cyclase inhibitor 8-bromo-4H-[1,2,4]oxadiazolo[3,4-c][1,4]benzoxazin-1-one NS2028
(2011)
Sulfur analogues of the soluble guanylate cyclase (sGC) inhibitor NS2028 1a are synthesized. Treating 8-bromo-2H-benzo[b][1,4]oxazin-3(4H)-one oxime (6) with 1,1′-thiocarbonyldiimidazole (1.1 equiv) gave the carbamothioate ...
Symmetric and asymmetric dinuclear manganese(IV) complexes possessing a [MnIV2(μ-O)2(μ-O2 CME)3+ core and terminal Cl- ligands
(2003)
The synthesis of new dinuclear manganese(IV) complexes possessing the [MnIV2(μ-O)2(μ-O2C Me)]3+ core and containing halide ions as terminal ligands is reported, [Mn2O2(O2CMe)Cl2 (bpy)2]2[MnCl4] (1
Regeneration of aged commercial three-way catalysts using CI-containing reagents
(2013)
The present work is focused on applying washing treatments using Cl-containing reagents, such as di-chloroacetic acid (DCA) for the first time, and 1,2-di-chloropropane, DCP (0.1 M) solutions in regaining the activity and ...
Effects of Pd particle size on the rates of oxygen back-spillover and CO oxidation under dynamic oxygen storage and release measurements over Pd/CeO2 catalysts
(2007)
A kinetic mathematical model has been applied to investigate for the first time the effects of Pd particle size on the rates of oxygen back-spillover and CO oxidation during Oxygen Storage Capacity (OSC) measurements under ...
Regeneration of aged commercial three-way catalytic converters
(2009)
The present work demonstrates for the first time that rejuvenation of the catalytic activity of full-scale aged commercial three-way catalytic (TWC) converters is feasible after treatment with weak oxalic acid solution ...
Macrocyclic cyclo[n]malonates - Synthetic aspects and observation of columnar arrangements by X-ray crystallography
(2006)
A variety of achiral and chiral macrocyclic oligomalonates were synthesised in a one-step procedure through condensation of malonyl dichloride with α,ω-diols. We have investigated the applicability of this method by varying ...
Stereochemistry of the [4 + 2] cycloadditions of trans,trans- and cis,trans-2,4-hexadiene to C60
(2002)
The [4 + 2] cycloaddition of trans,trans-2,4-hexadiene with C60 proceeds via a concerted mechanism with retention of stereochemistry in the cycloadduct 1a. However, when cis,trans-2,4-hexadiene reacts with C60, isomerization ...
Effective exchange coupling in alternating-chains of a π-extended 1,2,4-benzotriazin-4-yl
(2014)
Air stable 1,3,7-triphenyl-1,4-dihydrothiazolo[5′,4′:4,5] benzo[1,2-e][1,2,4]triazin-4-yl packs in 1D π stacks made of radical pairs with alternate short and long interplanar distances. The magnetic susceptibility exhibits ...
