Rationally designed P-chiral phosphine ligands are synthesized by the use of phosphine-boranes as the intermediates.
WebSep 1, 2007 · Phosphines 1. Introduction Significant achievements have been made in chiral transition metal complex-catalyzed stereoselective organic transformations [1]. Thus far, most of these chiral catalysts are a combination of optically pure ligands and transition metal ions in various oxidation states. WebPhosphine (PH₃) is a colorless, flammable, and explosive gas at room temperature that smells like garlic or decaying fish. Exposure to phosphine may cause, nausea, vomiting, stomach pain, diarrhea, thirst, muscle pain, difficulty breathing, and fluid in the lungs. Higher exposures and long-term exposure may cause serious harm.
