An Alternate Synthesis of Cyclic 1,3-Dinitramines

Article abstract of DOI:10.1021/jo00200a026

An alternate synthesis for cyclic 1,3-dinitramines has been developed.The new method involves the trapping of an in situ generated cyclic aminal with nitrous acid to generate a cyclic 1,3-dinitrosamine, which is subsequently converted to the cyclic 1,3-dinitramine by treatment with 100percent nitric acid or solutions of N2O5 in 100percent nitric acid.This alternate synthesis is superior for the synthesis of 5- and some 6-membered cyclic 1,3-dinitramines but not for 7-membered compounds.
