Abstract

Cubane-type clusters [Fe4S4 (SR*) 4] 2− containing chiral thiolate ligands with R*= CH (Me) Ph (1), CH2CH (Me) Et (2), and CH2CH (OH) CH2OH (3) have been prepared by ligand substitution in the reaction systems [Fe4S4 (SEt) 4]/R* SH (1− 3, acetonitrile) and [Fe4S4Cl4] 2−/NaSR*(3, Me2SO). The clusters 3-[RRRR] and 3-[SSSS] were obtained from enantiomerically enriched thiols. Identical 1H NMR spectra were obtained with racemic, R ...
