Abstract
Abstract Mechanistic studies show that nitroaryl ethers (3-nitroanisole, 3-nitrophenetole, n-butyl 3-nitrophenyl ether, 2-chloro-5-nitroanisole, 2-bromo-5-nitroanisole and 3,5-dinitro anisole) undergo nucleophilic aromatic photosubstitution with hydroxide ions through an SN23Ar* mechanism. An investigation of the quenching of exited states of nitroanyl ethers by bromide and thiosulfate ions in aqueous solutions is reported and lends support to the proposed SN23Ar* mechanism.
