89089-18-9, Name is 3-Bromo-6-chloropyridazine, belongs to pyridazine compound, is a common compound. Formula: C4H2BrClN2In an article, once mentioned the new application about 89089-18-9.

A practical and efficient base-catalyzed esterification has been developed for the facile synthesis of a broad range of esters from simple alcohols with unactivated tert-butyl esters. This protocol could be conducted at mild conditions, providing esters in high to excellent yields with good functional tolerance. Mechanistic studies provided evidence of an exchange of the tert-butyl alkoxide metal with the alcohol, producing a new alkoxide to participate in the transesterification reaction.
