Synthesis of 1, 3-diaryl Substituted Iodobenzene Derivatives
The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.
متن کاملA Solvent Free Route to the Synthesis of Diaryl Sulfoxides
The solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of Lewis acids such as aluminum chloride and ferric chloride on silica gel are described.
متن کاملSynthesis and beta-lactamase inhibitory activity of thiazolyl penam sulfones.
In our previous papers1»2), we described the structure-activity relationships of 6-(heterocyclyl)methylene penam sulfones (1) as a new class of /3-lactamase inhibitors and proposed a mechanism of enzyme inactivation for series 1. In continuation of these studies with series 1, we pursued the closely related structures in series 2, since they should follow a similar mechanistic pathway and shoul...
متن کاملPhotoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides
A novel method of photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides has been developed. Although the arylation reactions with triarylbismuthines are usually catalyzed by transition-metal complexes, the present arylation of diaryl diselenides with triarylbismuthines proceeds upon photoirradiation in the absence of transition-metal catalysts. ...
متن کاملRegioselective synthesis of chiral dimethyl-bis(ethylenedithio)tetrathiafulvalene sulfones
Enantiopure (R,R) and (S,S)-dimethyl-bis(ethylenedithio)tetrathiafulvalene monosulfones have been synthesized by the aerial oxidation of the chiral dithiolates generated from the propionitrile-protected precursors. Both enantiomers crystallize in the orthorhombic chiral space group P212121. They show a boat-type conformation of the TTF moiety, a rather rigid dithiin sulfone ring and the methyl ...
