  • The synthesis of organophosphorus compounds from elemental phosphorus is an inefficient process, using multiple steps, stoichiometric metal complexes and/or hazardous reagents such as chlorine gas. Here, a direct photocatalytic route to convert white phosphorus (P4) into phosphines and phosphonium salts is reported.

  • Highly diastereoselective Negishi cross-coupling reactions between 2-, 3- and 4-substituted cycloalkylzinc reagents and aryl iodides are described. In all cases, the thermodynamically most stable diastereomers of the cross-coupling products were obtained. NMR spectroscopy and density functional theory calculations were performed in order to rationalize the observed stereoselectivities.
