Abstract

The reaction of 4,7-dihydro-1,3-dioxepins II with nitryl chloride
in chloroform of light petroleum as a solvent gave a mixture of
5-chloro-6-nitro-dioxepans III and 5,6-dichloro-dioxepans IV. In
alkylnitriles as solvents, the corresponding 6-acylamino-5-chloro-
dioxepans VII were also formed. Hydrodechlorination of III in the
presence of triethylamine afforded 5-nitro-4,7-dihydro-1,3-dioxep-
