Mesoionics are heterocyclic compounds that have both positive and negative charges in delocalized form, have been attractive research area in recent years. These compounds have many applications in pharmacy, agriculture, construction of galvanic cell. Besides mesoionics display biological activity, they have been used as organic substrates in synthetic chemistry. In the mean time,such compounds were proposed to exhibit singlet fission which is an important concept related to increasing solar energy conversion. Even though such compounds were proposed to show singlet fission, these compounds (to our best knowledge) were not synthesized. This is probably due to the difficult synthetic pathways. Nevertheless, we have taken the challange to synthesize compound 1 in our laboratories. In this presentation, the synthesis of compound 1 from 2,5-dimethylpyrazine and characterization of 1 will be given.
