AbstractWe present a direct cross‐coupling reaction between arylaluminum compounds (ArAlMe2⋅LiCl) and organic halides RX (R=aryl, alkenyl, alkynyl; X=I, Br, and Cl) without any external catalyst. The reaction takes place smoothly, simply upon heating, thereby enabling the efficient and chemo‐/stereoselective formation of biaryl, alkene, and alkyne coupling products with broad functional group compatibility.
Nickel-catalyzed reductive cleavage of aryl alkyl ethers to arenes in absence of external reductant
The reductive cleavage of the C-O bonds of arylethers has numerous potential in organic synthesis. Although several catalysts that can promote the reductive cleavage of arylethers have been...
