Participation of Phosphine-Bound Aryls

Since the rate of transmetalation to 36 is in the order of Cl Br I [12], the choice of haloarene also served to minimize such side-reaction. [Pg.26]

Various combinations of catalysts, bases, and solvents allow the biaryl coupling of arylboronic acids with aryl halides and triflates if there are no side-reactions such as the hydrolytic B-C bond cleavage or the participation of phosphine-bound aryls [4] (Scheme 29). The representative conditions are summarized in the scheme and the effects of catalysts and bases on yields and side reactions are discussed in sections 3.1 and 3.2. [Pg.36]
