General description
1,3-Di-tert-butylimidazolium tetrafluoroborate is an N-heterocyclic carbene (NHC) compound that can be prepared by reacting paraformaldehyde with tert-butyl amine and hydrogen tetrafluoroborate (35% in water).
Application
1,3-Di-tert-butylimidazolium tetrafluoroborate may be used in the preparation of di-μ-iodobis(1,3-di-tert-butylimidazolin-2-ylidene)diiododipalladium(II), a palladium(II)-NHC complex, which can catalyze Mizoroki-Heck reaction.
