Abstract
According to Table1, the nucleofugality parameters obtained by this regression analysis range over eight orders of magnitude, from Nf= À 3.4 for 3, 5-dinitrobenzoate in 90% aqueous acetone to Nf= 4.7 for bromide in 80% aqueous ethanol. All slope parameters of chlorides, bromides, and 3, 5-dinitrobenzoates are close to 1.0. The slope parameter sf for trifluoroacetate is somewhat smaller in all solvents, indicating a slightly smaller ...
