The reactions of p-diiodobenzene with 5-C5H5)Fe(CO)2>- and 5-C5H5)W(CO)3>- were studied using a complex of electrochemical techniques (cyclic voltammetry, rotating ring-disk electrode and preparative scale electrolysis).For 5-C5H5)Fe(CO)2>- it was shown that aromatic nucleophilic substitution of either one or two iodine atoms in p-diiodobenzene for η5-cyclopentadienylirondicarbonyl can be performed through electrochemical activation of the aryl halide.The ratio of (η5-C5H5)Fe(CO)2C6H4I and (η5-C5H5)Fe(CO)2C6H4Fe(CO)2(η5-C5H5) was shown to depend strongly on the electrolysis conditions: electrode potential, electrolysis duration, etc.The yield of (η5-C5H5)Fe(CO)2C6H4Fe(CO)2(η5-C5H5) can be considerably increased when (η5-C5H5)Fe(CO)2C6H4I is taken as a starting compound.For 5-C5H5)W(CO)3I- the main product of the reaction with p-diiodobenzene is (η5-C5H5)W(CO)3I.
