Excited-State Deprotonation and H/D Exchange of an Iridium Hydride Complex

Excited-State Deprotonation and H/D Exchange of an Iridium Hydride Complex

Visible‐light irradiation of the hexafluorophosphate salt of [Cp*IrIII(bpy)H]+ (1, Cp*=η5‐C5Me5, bpy=2,2′‐bipyridine) results in excited‐state deprotonation to form the conjugate base [Cp*IrI(bpy)]. The H/D exchange reaction of 1 also occurs during photoirradiation of 1 in [D4]methanol in the steady...

Zusammenfassung:Visible‐light irradiation of the hexafluorophosphate salt of [Cp*IrIII(bpy)H]+ (1, Cp*=η5‐C5Me5, bpy=2,2′‐bipyridine) results in excited‐state deprotonation to form the conjugate base [Cp*IrI(bpy)]. The H/D exchange reaction of 1 also occurs during photoirradiation of 1 in [D4]methanol in the steady state (see picture).
