Abstract
Reactions of 4-oxocyclohexa-2,5-dienylidene (1) and two derivatives have been investigated using laser flash photolysis techniques. Photolysis of 4-diazocyclohexa-2,5-dien-1-one (4) in 1,1,2-trichlorotrifluoroethane allows the indirect detection of the corresponding carbene 1. The carbene reacts with triplet oxygen at close to the diffusion-controlled rate, forming the carbonyl O-oxide (λ max =470 nm). Reaction of triplet 1 with moderate concentrations of cyclohexane leads to formation of phenoxyl radical (λ max =395 nm)
