Photoelectrochemical cell for P–H/C–H cross-coupling with hydrogen evolution.

Photoelectrochemistry enables the formation of a variety of active intermediates for organic synthesis in an environmentally friendly manner. Herein, a photoelectrochemical cell is fabricated to realize activation of P–H/C–H bonds for cross-coupling hydrogen evolution. As compared with an electrochemical cell, nearly 90% external bias input is saved to drive the C–P bond construction with good to excellent yields. [ABSTRACT FROM AUTHOR]
