A solution-phase parallel method for the synthesis of 2-quinoxalinol salen ligands was designed and optimized. The synthesis begins with commercially available 1,5-difluoro-2, 4-dinitrobenzene (DFDNB) and employs a sequence of five straightforward and...

Alkylidenecyclopropanes readily convert into cyclobutene derivatives on treatment with catalytic amounts of PtCl 2 . The reaction is strongly accelerated when performed under an atmosphere of CO (1 atm). The resulting cyclobutenes are isolated in good to...
An environmentally benign and highly catalyst-substrate controlled synthesis of 1,2-disubstituted and 2-substituted benzimidazoles with outstanding selectivity has been developed through grinding a mixture ofo -phenylenediamines, suitable aldehydes and an...

We report the synthesis and characterization of a fluorescent probe (Hypo-SiF) designed for the detection of hypochlorous acid (HOCl) using a silicon analogue of fluorescein (SiF). The probe is regulated in an âoffâonâ fashion by a highly selective...

Since 2â-fluoro-5-methyl-β-l-arabinofuranosyluracil (l-FMAU) has been shown to be a potent anti-HBV agent in vitro, it was of interest to study the structureâactivity relationships of related nucleosides. Thus, a series of...

Well-defined poly(2,7-fluorene) derivatives have been prepared through palladium-catalyzed couplings between various 9,9-disubstituted or 9-monosubstituted 2,7-dibromofluorenes and 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9,9-dioctylfluorene....
Mo(CO) 3 (NC-t-Bu) 3 was found to be a suitable catalyst for the regioselective hydrostannation of several types of alkynes, giving preferentially rise to the α-stannylated products. These products are not available under radical reaction conditions or by...

A very convenient method for the synthesis of unsymmetrical ureas is described, based on isopropenyl carbamates. The synthetic efficiency of traditional methods for urea formation, such as use of phosgene or alkyl and aryl carbamates, is limited by the...

We have developed an efficient method for the synthesis of benzimidazoles via cascade reactions of o-haloacetoanilide derivatives with amidine hydrochlorides. The protocol uses 10 mol % CuBr as the catalyst, Cs 2 CO 3 as the base, and DMSO as the solvent,...
