Bis(imino)acenaphthene (BIAN) complexes of transition elements have been used widely in catalysis, invoking the involvement of the redox non-innocence of the ligand framework in the activity of the corresponding complexes. Several examples of elements of the p-block have been used to coordinate the BIAN ligand by Cowley, Fedushkin and others, some of which have been shown to be active in catalysis.<br/>New reports focused on the synergy of the non-innocent behavior of these ligands with main group elements remains a fruitful area ripe for discovery. We are interested in a 3-dimensional ligand framework, introduced by Guan and co-workers, that possesses a pendant pyridyl moiety positioned above the classic BIAN-ligand framework. Previously, this ligand was used to bind phosphorus and create phosphenium complexes which, when considering the pendant pyridyl group, were considered internal Lewis pairs. We were curious to introduce other p-block elements here, and to investigate the resultant ambiphilicity when using Group 13 elements within this unique ligand framework.<br/>This talk will introduce our synthetic approach to ambiphilic acenaphtho-1,3,2-diazaborole complexes, discuss our exploration of their redox non-innocence and give implications for their use in catalysis.
