Aryl chlorides functionalized Grignard reagent preparation

Relatively little is known of aryl Grignard reagents or aryllithium reagents, for example, produced from bromostyrene, but the former seems to have a tendency to polymerize during coupling [8]. On the other hand, the corresponding reagents prepared from vinylbenzyl chloride may in principle be used to couple a variety of functionalities to the styrene moiety. [Pg.206]

Fiirstner et al. reported the first effective cross-coupling reaction between aryl halides (functioning as the electrophile) and Grignard reagents derived from allg l halides. Under these reaction conditions, they observed an important effect of the halide/pseudo halide source used in the reaction (aryl-X Scheme 13.16). Notably, aryl chlorides exhibited the highest reactivity and are also cheaper and easy to prepare than the corresponding bromides and iodides. On the other hand, aryl iodides and bromides, which... [Pg.387]
