Cooperative Bond Activation and Catalysis by Nickel-Borane Complexes
The development of inexpensive, environmentally benign replacements for noble metal catalysts is now a major driver of research in inorganic chemistry. Towards this goal, this talk will detail a strategy for enabling facile, reversible H–H and Si–H bond activation reactivity at phosphine-supported nickel through the inclusion of a proximal borane center. The role of the ligand periphery in controlling this reactivity, the electronics of the Ni–B interaction, characterization of unusual intermediates, as well as catalytic applications will be discussed.
