Abstract
An all-inorganic biomimetic system bearing robust nitrogen-neighbored single-cobalt site/pyridinic-N site (Co-N4/Py-N) pairs can act cooperatively as an oxidase mimic. The catalyst enables scalable synthesis of O-silylated compounds including silanols, borasiloxanes, and silyl ethers via an unprecedented aerobic oxidation of hydrosilane.
