Characterization of Brønsted acid-base complexes by ¹⁹F DOSY.
A (19)F DOSY protocol for the determination of formula weights for acid-base complexes in solution has been developed. (19)F internal standards were chosen and were used to evaluate the formula weights of complexes in solution using simple diffusion coefficient (D)-formula weight (FW) analysis. This method has potential applications in characterization of reactive intermediates in catalytic asymmetric reactions.
