Experiments in the Colchicine Field. V. The Thermal and Photochemical Decomposition of Various 2-(β-Phenylethyl)-phenyldiazomethanes and 2-(γ-Phenylpropyl)-phenyldiazomethanes1
Photocatalyzed reactions of 2-(alkoxycarbonyl)benzenediazonium tetrafluoroborates with various alkenes afforded isochromanones in good yields, according to a mechanism that was investigated. The advantage of using highly soluble esters rather than carboxylic acids as starting compounds became evident when the reactions were performed under flow conditions. On the other hand, when 2-vinylbenzoic acid
A hydrogen atom transfer (HAT) step from acetone allowed the smooth generation of acetonyl radical that was then exploited as synthon in the mild formation of C–C bonds under flow conditions. The process was promoted by aryl radicals photocatalytically generated via single-electron transfer (SET) reduction of arenediazoniumsalts. The mechanism has been investigated by a combined experimental and computational
