Abstract

The d1 tungsten–alkylidyne radical [W(CPh)(dppe)2Cl]+ reacts with H2 to give the d0 hydride [W(CPh)(H)(dppe)2Cl]+, which on deprotonation yields the d2 photoredox chromophore W(CPh)(dppe)2Cl. This family of reactions results in a cycle by which renewable H2 provides the reducing equivalents for photochemical reductions.
