Transition-Metal-Free C–P Bond Formation via Decarboxylative Phosphorylation of Cinnamic Acids with P(O)H Compounds

摘要

A novel, transition-metal-free phosphorylation of cinnamic acids with P(O)H compounds has been developed via radical-promoted decarboxylation under mild conditions. This method provides simple, efficient, and versatile access to valuable (E )-alkenylphosphine oxides in satisfactory yields with a wide variety of substrates.
