Here, we describe the first efficient examples of this reaction. Conversion of 1-fluoro-2-iodo (or 1-chloro-2-iodo) to 1-fluoro-3-iodo (or 1-chloro-3-iodo) ferrocenes was ensured by suitably protecting the free 5-position. 2018-07-10 14:03:35 1- fluoro -2-iodo 1- chloro -3-iodo ferrocenes 1- fluoro -3-iodo 1- chloro -2-iodo 5- position
