Catalytic chemistry is one of the focal points for the development of environmentally benign organic transformations. It is true that the employment of catalysts in organic transformations comes wi...
The clusters [Fe4S4(SR)4]n− (n=3) generated electrochemically reduced imines to amines in a CH3CN/CH3OH solution. The correlations between the redox potentials of imines and the yields of the reductions were examined.

The intermolecular hydroamination of vinyl arene derivatives has been efficiently carried out using a tungstophosphoric acid (TPA) catalyst under solvent free and mild reaction conditions. The present protocol provides an environmentally benign, easy to handle and highly active solid acid catalyst for hydroamination of vinyl arenes. The catalyst yields both hydroamination and hydroarylation products and the selectivity mostly depends on the reaction conditions. (C) 2007 Published by Elsevier Ltd.
