A novel and facile DDQ-mediated dehydrogenation from natural rigid polycyclic acids or flexible alkyl acids to generate lactones is described. The formation of lactones proceeds by a radical ion mechanism, which has been...
The generation of hexamethylbenzenium radical cations as the key reaction intermediate in chabazite-type molecular sieve acids (i.e., H-SAPO-34 and H-SSZ-13) during the methanol-to-olefin process has been directly eviden...
Palladium-catalysed desulfitative addition of arylsulfinic acids to aryl and alkyl nitriles with 2,2 '-bipyridine as a ligand afforded a variety of aryl ketones via hydrolysis of ketimine intermediates.
Mid-functionalized ABC triblock copolymers with a short central B block were synthesized via the RAFT process, and further used as well-defined V-shaped copolymers to graft onto graphene oxide by coupling reactions.
Polycrystalline anatase TiO(2) films with high-reactivity {001} facets were grown on transparent conductive fluorine-doped tin dioxide substrates. The hydrothermal synthesis method relied on capping and stabilization of ...
Herein we report a general strategy to synthesize highly uniform and monodisperse rare earth fluoride nanocrystals through a novel OA/ionic liquid two-phase system, while water-soluble hexagonal NaREF(4) nanocrystals are...
A novel metal-free intramolecular oxidative decarboxylative coupling of primary alpha-amino acids with 2-aminobenzoketones under mild and neutral conditions was developed. Different quinazolines can be selectively obtain...
The ligand-free trifluoromethylation of arylboronic acids with a [Ph(2)SCF(3)](+)[OTf](-)/Cu(0) system has been carefully investigated. Aryl-, alkenyl- and heteroarylboronic acids with a variety of functional groups were...
Self-host heteroleptic green iridium(III) dendrimers have been designed and easily synthesized. Through tuning the carbazole dendron density, high efficiency is achieved using these dendrimers with a simple molecular str...
Mixed matrix membranes (MMMs) composed of a glassy polymer (polysulfone) and the flexible metal organic framework NH(2)-MIL-53(Al) exhibit excellent separation properties. In contrast to most reported membranes, CO(2)/CH...
The first direct intermolecular hydroamination/hydroalkylation of terminal alkynes catalyzed by In(OTf)(3) under one-pot conditions leading to the formation of conjugated ketimines in good yields is described.
An atom-economical purification protocol, using solution phase processing via ring-opening metathesis polymerization (ROMP) has been developed for the synthesis of tricyclic sultams. This chromatography-free method allow...
