Super strong base DBU® and DBN

Since the first industrial production of a compound with this structure by San-Apro in 1967, many researchers have introduced a number of unique reactions.
The stability of DBU, its strong basicity
even now, new applications are being discovered one after another, and many reports are being published.

DBU®

DBU is an organic compound that exhibits strong basicity, and was industrialized by San-Apro in 1967. It has a basicity comparable to sodium hydroxide and high solubility, and it demonstrates high catalytic activity and selectivity in a variety of organic synthesis reactions. This page describes its stability and diverse application possibilities.
