A series of m-fluoro-substituted benzhydryl chloridcjs, bromides, mesylates and Losylates 1-X to 5-X were prepared and subjected to solvolysis reactions in various solvents. The observed first-order rate constants ks(25 °C) were found to follow the correlation equation log ks(25 °C) = Sf(Nf + Ef), which allowed us to determine the electrofugalily parameters Ef for these destabilized benzhydrylium cations and the nucleofugality parameters Nf, S f for a series of leaving group/ solvent combinations.
