Efficient access to 3-alkyl-trifluoromethylbenzenes using Kumada's coupling reaction

3-Alkyl-trifluoromethylbenzenes are obtained in good yields by Kumada's coupling reaction between methyl or ethyl magnesium halide and 3-bromo-trifluoromethylbenzene derivatives in the presence of Ni-Xantphos catalyst.
