Irradiation of phenazine in acetaldehyde or propionaldehyde solution gave an N-acylated 5,10-dihydrophenazine.Acridine similarly gave 9-acyl-9,10-dihydroacridine, and 10-methylacridinium salt gave 9-acyl-10-methyl-9,10-dihydroacridine.In methanol N-acylated dihydrophenazines reacted with N-bromosuccinimide to give phenazine and methyl carboxylates in quantitative yield.
