Abstract

Abstract : Phosphine-appended-2, 2′-bipyridine serves as a platform for late-stage ligand modifications to install a series of functionalized arenes, including those containing Brønsted and Lewis acidic groups. Abstract : The ability of a phosphine-appended-2, 2′-bipyridine ligand ((Ph2 P)2 bpy) to serve as a platform for late-stage ligand modifications was evaluated using tetrahedral (Ph2 P)2 bpyFeCl2 . We employed a post-metalation Staudinger reaction to install a series of functionalized arenes, including those containing Brønsted and Lewis acidic groups. This reaction sequence represents a versatile strategy to both tune the ligand donor properties as well as directly incorporate appended functionality.
