    Alkyl Metal Complexes
    (Institute of Chemistry Ceylon, 2023-01) K. Sarath D Perera
    An alkyl-metal complex has at least one Metal Carbon (M-C) σ- or π-bond. Grignard reagent (RMgX) and LiR are the most common alkyl-metal reagents used in organic synthesis. ZnEt2 and EtZnI are the first metal alkyls prepared by Edward Frankland in 1848.

    Palladium Catalyzed Coupling Reactions
    (Institute of Chemistry Ceylon, 2023-01) K. Sarath D Perera
    Palladium complexes catalyze many types of organic reactions. It is particularly useful in forming carboncarbon bonds. For versatility, no other transition metal can compete with palladium. Palladium is readily available as Pd(II) chloride [PdCl2] Na2[PdCl4] or palladium acetate [Pd(OAc)2]; they are relatively cheap compared to rhodium and ruthenium salts.
