Chemistry of 1, 3-Dioxepins. I. Reaction of 4, 7-Dihidro-1, 3-dioxepins with Nitryl Chloride.

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

1; 3-dioxepins; nitryl chloride; addition; hydrodechlorination
