  • Desulfurization

    Due to its finely dispersed metal and high reactivity, SiGNa’s desulfurization method can remove sulfur from a wide range of sulfur species, including ones that are highly aromatic. With this method, desulfurizations can be performed at room temperature and pressure with simpler and safer reaction conditions.

    BENEFITS
    • Can be performed in either batch or continuous-flow reactor setup
    • Provides a smooth solution process at room temperature and pressure
    • Enhanced selectivity and kinetics of reaction
    • Capable of chemically removing sulfur from highly aromatic sulfur systems

  • Dissolving Metal Reduction

    Dissolving metal reductions performed using SiGNa’s stabilized reactive metals removes the hazards of alkali metal use and eliminates the need for cryogenic temperatures, high pressures, liquid ammonia, or additional catalysts. Our method improves yields, shortens reaction times, and simplifies workup procedures by enabling a smooth solution process at room temperature and pressure.

    BENEFITS
    • Enhanced selectivity and kinetics of reaction
    • Hydrogen can be supplied by either homogeneous or heterogeneous sources
    • Performed in either batch or continuous-flow reactor setup in safe solvents
    • By-products are non-hazardous and environmentally friendly

  • Ester Reduction

    An ester reduction using SiGNa’s materials results in alcohol conversion in high yield under mild reaction conditions. The simple aqueous workup, the quick reaction times, and the mild reaction conditions for this transformation make this new method better than modern methods for ester reductions.

    BENEFITS
    • Provides a smooth solution process at close to room temperature
    • Highly selective allowing more options for substrate functionalization
    • Avoids reaction workup issues associated with the formation of aluminum salts
    • No special equipment required for handling or processing
