Use of 1,10-phenanthroline in diiron dithiolate derivatives related to the [Fe–Fe] hydrogenase active site
Abstract
Treatment of [Fe2(µ-pdt)(CO)6] (pdt = S(CH2)3S) with 1,10-phenanthroline (phen) in refluxing toluene affords the asymmetric complex [Fe2(µ-pdt)(CO)4(phen)] (1); the protonation of 1 with HBF4·OEt2 in CD2Cl2 at 203 K has been monitored by 1H NMR.
