Photoinduced Hydride Reduction of 10-Methylacridinium Ion by Alkylbenzenes in the Presence of Perchloric Acid

Article abstract of DOI:10.1246/cl.1995.111

Photoinduced hydride reduction of 10-methylacridinium ion (AcrH⁺) by alkylbenzene occurs to yield 10-methyl-9,10-dihydroacridine in the presence of perchloric acid, while photoaddition occurs to yield 9-alkyl-10-methyl-9,10-dihydroacridine in the absence of perchloric acid.The hydride reduction of AcrH⁺ in the presence of perchloric acid proceeds via protonation of cridinyl radical produced by photoinduced electron transfer from alkylbenzene.
