Redox and "Antioxidant" Properties of Fe2(μ-SH)2(CO)4(PPh3)2.
Ontology highlight
ABSTRACT: The chemistry of Fe2(μ-SH)2(CO)4(PPh3)2 (2HH) is described with attention to S-S coupling reactions. Produced by the reduction of Fe2(μ-S2)(CO)4(PPh3)2 (2), 2HH is an analogue of Fe2(μ-SH)2(CO)6 (1HH), which exhibits well-behaved S-centered redox. Both 2HH and the related 2MeH exist as isomers that differ with respect to the stereochemistry of the μ-SR ligands (R = H, Me). Compounds 2HH, 2MeH, and 2 protonate to give rare examples of Fe-SH and Fe-S2 hydrides. Salts of [H2]+, [H2HH]+, and [H2MeH]+ were charact
