Abstract

The photoreactions of a luminescent osmium(VI) nitrido complex, [Os^VI(N)(L)(CN)₃]⁻ (OsN, HL = 2-(2-hydroxy-5-nitrophenyl)benzoxazole), with catechol (H₂Cat) and hydroquinone (H₂Q) lead to the cleavage of strong C–OH bonds (ca. 120 kcal mol⁻¹) of the dihydroxybenzenes with concomitant conversion of the coordinated cyanide to carbon monoxide.
