New Preparation and Reactions of Arylaluminum Reagents Using Barbier Conditions.

The reaction of various aryl bromides with magnesium turnings, LiCl and R2AlCl (R = Et, <italic>i</italic>-Bu) provides at room temperature arylaluminum reagents in high yields. These organometallic species undergo readily 1,4-additions, acylations, allylations, and Pd-catalyzed cross-couplings with various aryl iodides and bromides. [ABSTRACT FROM AUTHOR]
