标 题:Synthesis of bromobiphenyls

摘要:Bromobiphenyls (such as 2-fluoro-4-bromobiphenyl) are synthesized by reacting together a phenylboronic acid (such as phenylboronic acid) and a bromoiodobenzene (such as 2-fluoro-4-bromoiodobenzene). The reaction generally takes place with the aid of a catalyst (such as palladium in a zero valance state) and an inert solvent (such as fluorobenzene). Control of temperature is very important to obtain both an acceptable reaction rate and an acceptable level of terphenyl byproduct.
