Recent developments in the chemistry of azaferrocenes

The simplest heteroferrocene, azaferrocene, was first described in 1964, and until recently, the chemistry of these compounds has remained largely unexplored. This review will focus on recent advances in the chemistry of azaferrocenes including methods of azaferrocene synthesis and functionalization. The electrochemical behavior of azaferrocenes and their applications in catalysis and biology will also be emphasized here. (c) 2010 Elsevier B.V. All rights reserved.
