On the basis of preparation and characterization of [Fe]-H<sub>2</sub>ase models (2-COCH<sub>2</sub>-6-HOCH<sub>2</sub>C<sub>5</sub>H<sub>3</sub>N)Fe(CO)<sub>2</sub>L (<b>A</b>, L <b>=</b> η<sup>1</sup>-SCOMe; <b>B</b>, L <b>=</b> η<sup>1</sup>-2-SC<sub>5</sub>H<sub>4</sub>N), the chemical reactivities of <b>A</b> and <b>B</b> with various electrophilic and nucleophilic reagents have been investigated, systematically. Thus, when <b>A</b> reacted with 1 equiv of MeCOCl in the presence of Et<sub>3</sub>N in MeCN to give the η<sup>2</sup>-SCOMe-coordinated acylation product (2-COCH<sub>2</sub>-6-MeCO<sub>2</sub>CH<sub>2</sub>C<sub>5</sub>H<sub>3</sub>N)Fe(CO)<sub>2</sub>(η<sup>2</sup>-SCOMe) (<b>1</b>), treatment of <b>A</b> with excess HB...
