The invention discloses a method for preparation 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)-n-butylphosphine and in the presence of 2,2,6,6-tetramethylpiperidine 1-oxyl.
