A nickel-catalyzed reductive deoxygenation of aryl alkyl ethers and aryl pivalates has been developed. Hydrosilanes serve as a mild reducing agent. The present protocol allows the use of a pivalate group as a robust and traceless steering group in arene functionalization reactions.

Optimized conditions are developed for the conversion of electron‐deficient substrates to the corresponding amino‐substituted derivatives.
