The synthesis of novel PNN ruthenium pincer complexes based on 2, 2′- dipyridinemethane phosphine derivatives, as well as on 2, 2′-oxobispyridine phosphine ligands, and their reactivity toward dearomatization and cyclometalation are described. The dearomatized compounds 7a, b undergo cyclometalation to yield complexes 8a, b. In order for cyclometalation to proceed, the coordination sphere around the Ru center has to ...
