Streamlining Si-O bond formation through cobalt-catalyzed dehydrocoupling.

Herein we report a strategy for the synthesis of organosilicons, including siloxanes, silyl ethers, and aminosilanes, via Co-catalyzed dehydrogenative coupling between hydrosilanes and nucleophiles. This discovery represents an expansion of the synthetic toolkit for organosilicon synthesis, forging Si-O and Si-N bonds in the presence of cobalt complexes with salen-type ligands.
