The (2-pyridyl)sulfonyl group was found to be a multifunctional group in the preparation of structurally diverse fluorinated products. It not only facilitates the copper-mediated (or catalyzed) cross-coupling reaction between α-fluoro sulfone 4a and aryl iodides, but also enables further transformations of the coupling products 2.

The first palladium-catalyzed ring opening of norbornene to prepare methylenecyclopentane derivatives has been established. The process, which uses readily available aryl iodides, tosylhydrazones and norbornene as starting materials, likely takes place via tandem Heck-type coupling, palladium carbene migratory insertion, C-C bond cleavage and the β-hydride elimination pathway in a single synthe...

We herein describe the development of an efficient enantioselective catalytic system that promotes the arylation of secondary silanes. Our method involves treatment of secondary silanes and aryl iodides with a Pd(2)(dba)(3)-asymmetric phosphoramidite ligand system to afford optically active tertiary silanes with good enantioselectivities.

Following on the heels of remarkable lead halide perovskite optoelectronic materials, interest in lead-free perovskites has grown rapidly past decade. Double halides with general formula A2MIMIIIX6 (where A is a large monovalent cation site, MI univalent metal, MIII trivalent and X halide) represent one promising classes such these, iodides are particularly interesting since their band gaps exp...

A photoinduced reaction between TMDPO (diphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide) and perfluoroalkyl iodides successfully affords P-(perfluoroalkyl)diphenylphosphines as promising ligands for recyclable catalysts. Interestingly, the perfluoroalkylation reaction involves the reduction of phosphorus(V) compounds to phosphorus(III) species. The advantages of the present reaction include the...

The carbamate (-O2CNR2) function is an excellent directing group for palladium-catalysed direct arylation reactions giving both protected or free mono- or di-substituted phenols, as well as an example of a dibenzopyranone, depending on coupling partners (aryl iodides or diaryliodonium salts) and conditions.

A new, mild, and environment friendly process for the reduction of S-alkyl-thionocarbonates, iodides and related compounds to the corresponding hydrocarbons at room temperature with good to excellent yields is described. This method uses a trialkylborane in excess (Et3B or Bu3B) and air.

A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of d...
