Keywords: quinoidal tetrazine preparation; bisdimethylpyrazolyltetrazine reaction nitrogen heterocyclic carbene precursor; imidazolium reaction tetrazine bisdimethylpyrazolyl. Let’s learn more about this compound (cas:286014-53-7).
A series of different N-heterocyclic carbenes (NHCs) were reacted with 3,6-bis(3′,5′-dimethylpyrazolyl)tetrazine in the presence of an inorganic carbonate to provide access to a hitherto unprecedented compound class. The formed tetrazine derivatives, e.g. I, bearing the NHC in the 3-position and an oxygen in the 6-position show a quinoidal-like structure, according to phys. examinations and X-ray crystallog.
