摘要

Continuing the study of electron transfer reactions of polypyridiniomethylstyrene chloride (PSPyCl)

the reduction of nitro-compounds by the PSPyCl-Zn system was investigated. In general azoxy compounds were obtained as chief intermediate product of reduction. Reduction of nitrobenzo-15-crown-5 and its homologues give a new class of bis-crown ether compounds——azoxy-bisbenzocrown ethers. Azoxybisbenzocrown ethers undergo photoinduced trans-cis isomerization

which is reversible on irradiation with UV and on storage in darkness

similar to the case of azobis crows ethers.Investigation of solvent extraction of various cations by azobiscrown ether isomers shows that cis-azoxybisbenzo-15-crown-5 exhibit good selectivity toward Nd3+ from other rare earth cations.
