At room temperature, nickel catalysts based on the new phosphoramidite (11bR)-N-[(S)-1-(naphthalen-1-yl)ethyl]-N-[(S)-1-(naphthalen-2-yl)ethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine provide excellent selectivities for 3-arylbut-1-enes (93–99%) with high enantioselectivities (90–95% ee) and TOFs (up to 8300 h−1) in the hydrovinylation of electron-rich and electron-poor vinylarenes.
