چکیده

We report the isolation, characterization, and reactions of the unsaturated complex L(tBu)Co (L(tBu) = bulky β-diketiminate ligand). The unusual slipped κN,η(6)-arene binding mode in L(tBu)Co interconverts rapidly and reversibly with the traditional κ(2)N,N' ligation mode upon binding of Lewis bases, making it a "masked" two-coordinate complex. The mechanism of this isomerization is demonstrated using kinetic studies. L(tBu)Co is a stable yet reactive synthon for low-coordinate cobalt(I) complexes and is capable of cleaving the C-F bond in fluorobenzene.

Insertion reactions of a two-coordinate iron diaryl with dioxygen and carbon monoxide.

The iron(II) diaryl FeAr'2 (1) (Ar' = C6H3-2,6-(C6H3-2,6-(i)Pr2)2) reacts cleanly with O2 or CO to afford the monomeric, two-coordinate bis(aryloxide) Fe(OAr')2 (2) or the eta2-acyl-carbonyl complex (eta2-Ar'C=O)2Fe(CO)2 (3) via oxygen or CO insertion into the Fe-C bonds; complex 2 has a strictly linear geometry and shows remarkable resistance to O2 oxidation.
