The d(1) tungsten-alkylidyne radical [W(CPh)(dppe)(2)Cl](+) reacts with H-2 to give the d(0) hydride [W(CPh)(H)(dppe)(2)Cl](+), which on deprotonation yields the d(2) photoredox chromophore W(CPh)(dppe)(2)Cl. This family of reactions results in a cycle by which renewable H-2 provides the reducing equivalents for photochemical reductions.
