An electron spin resonance study of the 2,5-diphenylchalcophene radical ions

The 2,5-diphenylchalcophene radical ions (chalcogen = O, S, Se, Te) have been prepared by the action of alkali metal in 1,2-dimethoxyethane (anions), or by the action of sulphuric acid or thallium(III) trifluoroacetate in trifluoroacetic acid (TFAH) (cati

Nickel-catalyzed and Li-mediated regiospecific C-H arylation of benzothiophenes

A nickel-based catalytic system for the regiospecific C2-H arylation of benzothiophene has been established. NiCl2(bpy) is used as a catalyst in combination with LiHMDS as a base in dioxane. The catalytic system is applicable to a variety of functionalized benzothiophenes, as well as other heteroarenes including thiophene, benzodithiophene, benzofuran and selenophene in combination with iodo aryl electrophiles. The role of LiHMDS as a uniquely potent base and a postulated mechanism are discussed. The applicability of this system is finally demonstrated for the synthesis of an intermediate of an active pharmaceutical ingredient.

Transition-Metal-Free Highly Chemoselective and Stereoselective Reduction with Se/DMF/H2O System

A novel metal-free reduction system, in which H2Se (or HSe-) produced in situ from Se/DMF/H2O acts as the active reducing species, has been developed. By using water as an inexpensive, safe, and environmentally friendly surrogate as the hydrogen donor, this new reduction system incorporating Se/DMF/H2O displayed high selectivity and good activity in the reduction of α,β-unsaturated ketones and alkynes. Therefore, this reduction system has great potential to be a general and practical reduction methodology in organic transformation.
