Aryl halides or triflates can be coupled with diboronyl reagents using transitionmetal catalysts. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Transitionmetal oxides are also frequently used as pigments in paints and plastics, most notably titanium di...
In most cases quantitative conversions of aryl halides were observed within short reaction time, associated with good to high isolated yields (30‐95%). In addition to be suitable solvents for this application, alkyl levulinates can be recovered and reused, offering when associated to heterogeneous...

These compounds, the acid halides, the acid amides, and the nitriles are included in the group 60 designated as the acid derivatives of the dicarboxylic acids. in which R is a radical from the class consisting 10 of hydrogen, alkyl, aralkyl, aryl and alicylic radicals. 3. The amide ...
The Suzuki coupling mechanism follows a catalytic cycle involving three primary steps. These are oxidative addition, transmetalation, and reductive elimination. The first step is the oxidative addition of aryl halides to the Pd(0)complex to give intermediate 1, a Pd(2)species. Under the action ...

A chiral allylic stannane, easily accessible via an enantiotopos differentiating deprotonation of a 1-phenyl-1-alkenylcarbamate, is coupled with different aryl halides. In this enantiospecific Stille reaction a 畏3-bound palladium species is assumed to eliminate either to an arylated 1-alkenyl ...
Depending on the reaction conditions, it occurs either as chlorination of the aromatic ring or as oxidation to give sulfoxide.doi:10.1007/BF01431147K. S. NosovA. V. LalovM. P. EgorovO. M. NefedovKluwer Academic Publishers-Plenum PublishersRussian Chemical Bulletin...
As selenium transfer reagents, arylselenoamides react with a variety of alkyl halides in ethanol under mild conditions to give dialkyl diselenides in excellent yields. Similarly, alkyl halides treated with selenourea form dialkyl diselenides. The possible mechanism is discussed....
