A super reduced Fe4S4 cluster with a sulfur based radical (1) which evolves H2S on treatment with acid under ambient conditions has been synthesized and characterized. The EPR spectrum of 1 resembles the CO inhibited, reduced Fe-S cluster of Clostridium pasteurianum W5 hydrogenase and the Fe4S4 center of the wild-type enzyme, IspH treated with HMBPP or IPP.

    Is it surprising that these clusters evolve H2S? At least they provide a yield for the compound of interest this time.
