The reaction of 13-H-elimination in organic nitrates, involving detachment of the nitric acid molecule with the formation of unsaturated compounds [2-4], is still insufficiently studied from the standpoint of preparative chemistry. There are only a few papers describing the synthesis of 2-nitrosoolefins [5-7], fumaric acid [8], 2-nitroolefins (polymerized in the course of the reaction)[9], unsaturated steroidal nitro compounds [! 0], and nitro (dinitro)- ...
