Abstract

Zirconium dodecyl sulfate [Zr(DS)4] is an efficient catalyst for the aminolysis of epoxides in water at pH 5.0. Epoxides and anilines were used and the corresponding β-amino alcohols were isolated in generally high regioselectivity and excellent yields.

The pH value reported is that measured in the clear aqueous layer completely separated from the organic one. A pH meter equipped with a combined refillable pH electrode and with an autocompensating temperature control (ATC) probe was used.
