Visible-light irradiation of the hexafluorophosphate salt of [Cp*lrIII(bpy)H]+ (1, Cp*=η-C 5Me5, bpy=2,2′-bipyridine) results in excited-state deprotonation to form the conjugate base [Cp*lrI(bpy)]. The H/ D exchange reaction of 1 also occurs during photoirradiation of 1 in [D 4]methanol in the steady state (see picture).
