Abstract: | Investigation of the reactions of phosphorylated 2-nitro- and 2-bromo-2-nitroethenes with furan showed that bis(2-chloroethyl) 2-nitroethenylphosphonate reacts with this heterocycle according to the pathway of diene condensation, while in the case of 2-bromo-2-nitroethenylphosphonate by two pathways, the complete diene synthesis accompanied by aromatization, and the electrophilic substitution at C2-atom of the furan with the subsequent partial dehydrohalogenation. |
