Application

3,5-Dimethylphenylmagnesium bromide solution can be used:
  • As a starting material for the synthesis of diarylborinic acids, which on Suzuki coupling with vinyl triflate yield penultimate methyl ester.
  • To prepare 3,5-dimethyl-p-terphenyl by reacting with biphenylsulfonate in the presence of dppfNiCl2 catalyst.
