Abstract
New ferrocenylamine derivatives 1,3-C6H4(CONHFc)(2) (3), 1,3-C6H4(SO(2)NHFc )(2) (4), and 1,3-C6H4(CONHFc)(COOEt) (5) (Fc = ferrocenyl), readily synthe sized from FcNH(2) and the appropriate acid dichlorides, bind chloride 1:1 as shown by H-1 NMR, FT-IR, and cyclic voltammetry. NMR titrations gave ass ociation constants as high as 9.5 x 10(3) (for 4 . Cl-). Cyclic voltammetry of 4 . Cl- vs 4 shows a 20 mV negative shift for the ferrocene wave, indic ating Cl- binding. An improved synthesis of FcNH(2) is reported.
