Comprehensive Summary

With the increasing demand for homoallylic silanes and allylic silanes, the highly efficient and regioselective hydrosilylations of conjugated dienes are urgently needed. Herein, we developed a Ni-catalyzed regiodivergent hydrosilylation of aromatic conjugated dienes by adjusting the temperature and ligands. Under low temperature (–30 °C), an eternal-ligand-free system (Ni/t-BuOK) can efficiently facilitate the 3,4-anti-Markovnikov hydrosilylation to provide homoallylic silanes via electrophilic activation process; under room temperature (25 °C), a ligand-controlled system (Ni/t-BuOK/PPh3) can eventuate the 3,4-Markovnikov hydrosilylation to produce allylic silanes via Chalk-Harrod process. Both systems are compatible with various conjugated dienes and primary silanes in excellent yields and regioselectivities.image
