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.

developed by copper‐catalyzed decarboxylative coupling of alkenyl, alkynyl carboxylic acids, and N‐benzylproline, respectively, with R2P(O)H (see scheme). All classes of products are important precursors for preparation of biologically active molecules and various phosphorus ligands. This finding represents the first example of copper‐catalyzed decarboxylative coupling to construct CP bonds.
