Abstract

With the aim of developing new IR-detectable metal-carbonyl tracers for the amino function, we have synthesized W(CO)(5) complexes of 4-oxo-4-(2,5-dimethylazaferrocen-1'-yl)butanoic acid (2) and 5-oxo-5-(2,5-dimethylazaferrocen-1'-yl)pentanoic acid (3) by AlCl3-catalyzed Friedel-Crafts reaction Of W(CO)(5)-2,5-dimethylazaferrocene (1) with succinic or glutaric anhydride. Complexes 2 and 3 are ...
