摘要：
The invention discloses a method for preparation of alkylated or fluoro, chloro and fluorochloro alkylated compounds by a heterogeneous Pt/C-catalyzed alkylation or fluoro, chloro and fluorochloro alkylation with alkyl halides or with fluoro, chloro and fluorochloro alkyl halides in the presence of Cs2C03 or CsHC03.
