Shuffle off the classic β-Si elimination by Ni-NHC cooperation: implication for C–C forming reactions involving Ni-alkyl-β-silanes

Via a cooperation of NHC, Si substituents and a M center, β-Si elimination was attenuated, revealing a new way to attain a high Ni-β-SiR3 : Ni-σ-SiR3 ratio. The scope is illustrated by a head-to-tail vinylsilane-α-olefin hydroalkenylation.
