Abstract

The invention discloses a method for preparations of fluoro, chloro and fluorochloro alkylated compounds by homogeneous Pd catalyzed fluoro, chloro and fluorochloro alkylation with fluoro, chloro and fluorochloroalkyl halides in the presence of di(1-adamantyl)-adamantyl-n-butylphosphine and in the presence of 2,2,6,6-tetramethylpiperdine 1-oxyl.
