Abstract

The complexes (cnt)₂[Fe(nta)Cl₂], where nta = nitrilotriacetate and cnt = Et₄N⁺ or PyH⁺, catalyze the air oxidation of thiols to disulfides under ambient conditions. Dithiols are converted to linear and cyclic oligomers that differ in their terminal groups as a function of the counterion, cnt. Cysteine ethyl ester was converted to the corresponding cystine diethylester in high yield.
