摘要

Reactions of 1-chloro-4-nitrobenzene (1) with alkoxide ions in the parent alcohols do not afford satisfactory yields of the expected alkyl 4-nitroaryl ether except in the case of the short- chain primary alcohols. We report that in the model reaction of 1 with KOH in 2-propanol good yields of 1-isopropoxy-4nitrobenmne (2) are obtained provided BulNBr or alkali ion complexing agents such as 18-crown-6, Carbowax 20M, MPEG 5000, and Triton X-100 ...
