Polypyrazolylborate copper(i) complexes as catalysts of the homogeneous and heterogeneous styrene epoxidation reaction
Abstract
The complexes BpCu (1) and Tp*Cu (2) catalyse the transformation of styrene into styrene oxide using Oxone as the oxidising agent; the use of silica gel-supported 1 or 2 as heterogeneous catalysts affords similar results, using water as the sole solvent.
