N-(1,1-dihydro)polyfluoroalkyl substituted triphenylmethane dyes

Transition‐Metal‐Free Synthesis of Polyfluoro‐Polyarylmethanes via Direct Cross‐Coupling of Polyfluoroarenes and Benzyl Chlorides

“…As a significant member in families of polyarylmethanes, fluorinated polyarylmethanes such as polyfluoro di ‐ and tri‐ arylmethanes represent a distinct class of fluorinated compounds due to their marvelous properties in liquid crystals, [15] dyes, [16] tri ‐aryl carbenium ions [17] . Although diverse approaches have been developed to fulfill the functionalization of polyfluoroarenes via selective C−H/F cleavage of polyfluoroarenes, [18] the efficient synthesis strategies to access polyfluoro di ‐ and tri ‐arylmethanes are still a challenge.…”
