Direct observation of an acyl nitroso species in solution by time-resolved IR spectrocopy.
Benzoyl nitroside (5) was generated in solution by laser photolysis of 3,5-diphenyl-1,2,4-oxadiazole-4-oxide (4) and studied by time-resolved infrared spectroscopy. The second-order rate constants for reaction of 5 with diethylamine and 1,3-cyclohexadiene were determined to be (1.3 +/- 0.5) x 10(5) M(-1) s(-1) and (6.0 +/- 0.5) x 10(3) M(-1) s(-1), respectively. The formation of nitroxyl (HNO), a product of the reaction of 5 with diethylamine, was also observed.
