Abstract
Oxidative insertion of the In(i) 'carbene analogues', [In{N(Dipp)C(Me)} 2CH] (Ar = Dipp = 2,6-iPr2C6H 3; Ar = Mes = 2,4,6-Me3C6H2) into the Fe-I bond of [CpFe(CO)2I] occurred cleanly and under mild conditions to yield the In(iii) compounds [CH{(CH3) 2CN-2,6-iPr2C6H3} 2In(I)FeCp(CO)2] and [CH{(CH3) 2CN-2,4,6-Me3C6H3} 2In(I)FeCp(CO)2], which have been fully characterised in solution and the solid state. Attempts to abstract the iodide anion from [CH{(CH3)2CN-2,6-iPr2C 6H3}2In(I)FeCp(CO)2] to form cationic species containing a coordinated indium diyl were unsuccessful and resulted in a complex mixture of products from which two ionic species were isolated. Neither cation was found to contain indium by X-ray crystallographic analysis. These observations were indicative of ill-defined decomposition pathways as have been noted by previous workers. A further attempt to form a cationic iron species containing a coordinated [In{N(Dipp)C(Me)}2CH] fragment resulted in oxidation of the iron centre from Fe(ii) to Fe(iii), with deposition of indium metal, and the isolation of a cationic Fe(iii) β-diketiminate complex.
