A novel type of highly efficient chiral sulfinamide bisphosphine catalysts (Wei‐Phos) were developed. These could be easily prepared from commercially available starting materials. Wei‐Phos has shown good performance in the very challenging intermolecular cross‐Rauhut–Currier reactions of vinyl ketones and 3‐acyl acrylates or 2‐ene‐1,4‐diones, leading to the R‐C products in high yields with up to 99 % ee under 2.5–5 mol% catalyst loading. The highly regio‐ and enantio‐selective cross‐Rauhut–Currier reactions of 2‐ene‐1,4‐diones and vinyl ketone have yet reported so far.
