Abstract

Abstract The basicity of isomeric bromoethylamines having a CF 3 substituent in the α-and β- positions with respect to the amino group was studied. According to potentiometric titration in H 2 O, CH 3 NO 2, and CH 3 CN, the basicity of α-trifluoromethylamines is 4–5 orders of magnitude lower than that of β-trifluoromethyl isomers. Quantum-chemical calculations (AM1) showed that the decrease in the basicity of α-trifluoromethylamines does not ...
