Cu‐Catalyzed Controllable Single and Double Hydrophosphination of Trifluoromethyl 1,3‐Enynes †
Fluorinated organophosphorus compounds are highly valuable in transition‐metal catalysis and medicinal chemistry. Despite their significance, synthetic methods through catalytic hydrophosphination of β‐CF 3 ‐1,3‐enynes remain unexplored, particularly for divergent synthesis of structurally distinct phosphine deri...
