Oxidative C-O bond cleavage of dihydroxybenzenes and conversion of coordinated cyanide to carbon monoxide using a luminescent Os(VI) cyanonitrido complex

摘要

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 (H(2)Cat) and hydroquinone (H(2)Q) 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.
