Table 4 Substrate scope for enantioselective synthesis of silicon-stereogenic allyl vinylsilanes 4a.

From: Nickel(0)-catalyzed divergent reactions of silacyclobutanes with internal alkynes

  1. aInternal alkynes 2 (0.2 mmol), SCBs 1 (0.4 mmol), Ni(cod)2 (0.02 mmol), L20 (0.04 mmol) in 2-MeTHF at 60 °C for 24 h. Values represent isolated yields. The er value was determined by chiral HPLC.
  2. bL23 (0.04 mmol) as ligand at 80 °C for 24 h.
