Improving Our World... One Discovery At A Time

Alkene/Alkyne Reduction

Classic Method

Typical hydrogenation reactions result in the addition of hydrogen (H2) to unsaturated organic compounds in the presence of a metal catalyst. These hydrogenations are limited to specific equipment and expensive precious metal catalysts or difficult reaction conditions with cheaper catalyst alternatives.

Phenanthrene Hydrogenation

Problems

  • Requires catalysts, either expensive precious metal or less-active catalysts
  • Conditions utilize long conversion times and high temperatures
  • Handling of flammable high-pressure hydrogen gas
  • Safety and economic issues due to special equipment

SiGNa’s Method

The SiGNa hydrogenation method does not require expensive catalysts or high pressure hydrogen to complete the conversion due to its electron-donating mechanism. SiGNa’s materials and method perform hydrogenations in a smooth solution process at room temperature and pressure utilizing simple sources of hydrogen (water, alcohol, ammonium phosphate, etc.).

Phenanthrene Hydrogenation

Stilbene Hydrogenation

Benefits

  • Performed in either batch or continuous-flow reactor setup in safe solvents
  • Provides a smooth solution process at room temperature
  • Hydrogen can be supplied by either homogeneous or heterogeneous sources
  • Enhanced selectivity and kinetics of reaction
