Practical methylation of aryl halides by Suzuki-Miyaura coupling

A number of aryl halides (X = Cl, Br, I) can be converted to the corresponding toluenes in an operationally simple manner using trimethylboroxine (TMB) as a partner for palladium-catalysed Suzuki-Miyaura coupling. (C) 2000 Elsevier Science Ltd. All rights reserved.
