Abstract FeI 2 (CO) 3 PPh 3 , which usually used as the precursor of [Fe]-hydrogenase, was firstly used as catalyst in one-step hydroxylation of phenol to dihydroxybenzenes. It was found that the reaction can be conducted smoothly in aqueous phase at ambient temperature (25 °C). In the optimum conditions, the conversion of phenol is 26.7% and selectivity of DHB is 80.0%. The possible mechanism was investigated and proposed. The apparent kinetics study shows that it is a pseudo second order reaction and activation energy E a is 66.36 kJ/mol. Graphic Abstract
