The first one-pot synthesis of a chiral pentakis-adduct of C60 utilising an opened-structure malonate tether
(2013)
A pentakis-adduct of C60 with an incomplete octahedral addition pattern was synthesised via a one-pot procedure using a tether equipped with five malonate moieties. The five-fold Bingel cyclopropanation of C60 was completely ...
Synthesis of 2-(4H-1,2,6-thiadiazin-4-ylidene)malononitriles
(2014)
The base-free TiCl4-mediated condensation of 3,5-disubstituted-4H-1,2,6-thiadiazin-4-ones 8 with malononitrile affords 20 difficult to access (3,5-disubstituted-4H-1,2,6-thiadiazin-4-ylidene)malononitriles 7. The reaction ...
Silver mediated direct C-H arylation of 3-bromoisothiazole-5-carbonitrile
(2014)
Palladium catalyzed direct C-H arylation of 3-bromoisothiazole-5-carbonitrile with aryl/hetaryl iodides in the presence of AgF gave 13 4-aryl/hetaryl-3-bromoisothiazole-5-carbonitriles. The scope of this arylation was ...
The reaction of 4,5-Dichloro-1,2,3-dithiazolium chloride with sulfimides: A new synthesis of N-Aryl-1,2,3-dithiazolimines
(2009)
N-Aryl-S,S-dimethylsulfimides 3 (Ar = 4-NO2C6H4), 4 (Ar = Ph) and 5 (Ar = 4- Tol) react with Appel salt 1 to give the corresponding N-aryl-(4-chloro-5H-1, 2,3- dithiazolylidene)benzenamines 8 (Ar = 4-NO2C6H4), 9 (Ar = Ph) ...
Investigation of the stability of polyelectrolyte multilayer coatings in open-tubular capillary electrochromatography using laser scanning confocal microscopy
(2005)
A simple polyelectrolyte multilayer (PEM) coating procedure was used for the development of stable modified capillaries. PEM coatings were constructed in fused-silica capillaries using alternating rinses of cationic and ...
Enantioseparations in open-tubular capillary electrochromatography: Recent advances and applications
(2016)
This review highlights recent advances and applications in open-tubular capillary electrochromatography (OT-CEC) for enantioseparations during the last decade. Although extensive research has been conducted in the area of ...
Synthesis of triazafluoranthenones via silver(I)-mediated nonoxidative and oxidative intramolecular palladium-catalyzed cyclizations
(2011)
Silver(I) fluoride (AgF)-mediated intramolecular nonoxidative and oxidative palladium-catalyzed cyclizations of 1,3-diphenyl- and 8-iodo-1,3- diphenylbenzo[e][1,2,4]triazin-7(1H)-ones 6a (R = H) and 7a (R = I) afford a new ...
Regiospecific synthesis of 5,7-disubstituted quinoxalino[2,3-b]phenazines
(2002)
Hydrogenation of the readily prepared dinitrobenzenediamines 7 followed by air oxidation affords the green colored 5,7-disubstituted-5H,12H-quinoxalino[2, 3-b]phenazines 3 in good yields. Mechanistic rationale, compound ...
MRI-based morphological modeling, synthesis and characterization of cardiac tissue-mimicking materials
(2012)
This study uses standard synthetic methodologies to produce tissue-mimicking materials that match the morphology and emulate the in vivo murine and human cardiac mechanical and imaging characteristics, with dynamic mechanical ...
Nanoscopic cationic methacrylate star homopolymers: Synthesis by group transfer polymerization, characterization and evaluation as transfection reagents
(2004)
Seven star polymers with degrees of polymerization (DPs) of the arms from 10 to 100 and dimensions in the nanometer range were prepared using sequential group transfer polymerization of 2-(dimethylamino)-ethyl methacrylate ...
