Description

Application

1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) is an amidine base commonly used in the base-mediated eliminations, condensations, esterifications, isomerizations, carboxylations and carbonylations.
It is used in the preparation of supertetrahedral chalcogenide clusters and single crystals of polymer-chalcogenide composites.
It also acts as a catalyst for the regioselective Friedel-Crafts C-acylation of pyrroles.

Other Notes

Amidine base used for dehydrohalogenation reactions to olefins
