摘要：

Inspired by natural [Fe]-hydrogenase, mono-iron complex Fe-II(CO)(3)I-3-[trimethylpyridine-H] (complex 1) was synthesized and characterized by IR, H-1 NMR, C-13 NMR, EA. The singe crystal structure of the complex 1 was characterized by single crystal X-ray diffraction. The hydroxylation reaction of phenol to dihydroxybenzene was conducted using complex 1 as catalyst in aqueous phase at ambient temperature. Under the optimum conditions, the phenol conversion was 20.5%, dihydroxybenzene selectivity was 83.7%, catechol/hydroquinone (mol/mol) was 2.6. Complex 1 can be a promising catalyst for hydroxylation of phenol to dihydroxybenzene because of mild reaction conditions and good catalytic performance.
