It acts a mediator of radical reactions and considered to be a nontoxic substitute for tri-n-butylstannane in radical reactions. It forms complexes with transition metals and main group elements. Further, it is utilized in carbon-carbon bond forming reactions.

    Solubility
    Miscible with pentane, ether, toluene and tetrahydrofuran. Sparingly miscible with acetone and acetonitrile. Immiscible with water.
