Binuclear Aroyl and Carbamoyl Complexes of Iron:  X-ray Crystal Structures of [Fe2(μ:σ,σ‘-OCR)2(CO)5(PPh3)] (R = C6H3Me2-2,6, NiPr2)

Abstract: The syntheses of two bimetallic complexes [Fe2(μ:σ,σ‘-OCR)2(CO)5(PPh3)] [R = C6H3Me2-2,6 (1), NiPr2 (2)] are described, the latter by a variety of routes. A comparison of the structural effects of the aroyl and carbamoyl bridging ligands upon the unsymmetrically bridged diiron core follows from crystallographic studies on both complexes.

“…Compounds of the type [(CO) 3 Fe(μ-RCO) 2 Fe(CO) 3 ] including 4 have been known for more than 30 years, but their number is limited to three examples with R = Me, Ph, and C 9 H 19 . More common are the substituted compounds [(CO) 3 Fe(μ-RCO) 2 Fe(CO) 2 D] with one donor ligand at the oxygen-coordinated iron atom and related compounds with R = carbamoyl, alkoxycarbonyl; further examples have been obtained recently by the group of Hill and Salaün and in our group by reacting an iron carbamoyl complex with Lewis acids . In all cases the compounds were obtained by oxidation of a mononuclear acyl anion [(CO) 4 FeC(O)R] - , and the mechanism of formation is still unclear.…”

“…Most of them are prepared by oxidation of anions [(CO) 4 Fe{C(O)R}] À with one electron oxidants (R = CH 3 , C 6 H 5 [11a,20,21]; C 9 H 19 [21c,21d]; N(C 2 H 5 ) 2 [22] N iÀ Pr 2 [20,23]. In the present process, as observed for the reaction of [(CO) 4 Fe{C(O)CH 3 }] À with oxalyl chloride [20], or when [(CO) 4 Fe{C(O)N iÀ Pr 2 }] À is allowed to react with ClC(O)N iÀ Pr 2 [20] or HgCl 2 [23] the organic chloride can play the part of the oxidant.…”
