Ligand redistribution reactions of Me 2Ga(C 5H 5) and MeGa(C 5H 5) 2

Abstract

The compounds Me 2Ga(C 5H 5) and MeGa(C 5H 5) 2 have been prepared by ligand redistribution reactions between appropriate stoichiometric quantities of Ga(C 5H 5) and GaMe 3. Both compounds have been demonstrated by 1H NMR spectral studies to be unstable in solution and to form symmetrized products by ligand redistribution reactions. Thus, Me 2Ga(C 5H 5) forms GaMe 3 and MeGa(C 5H 5) 2 as primary products whereas MeGa(C 5H 5) 2 decomposes to Ga(C 5H 5) 3 and Me 2Ga(C 5H 5). The compound Me 2Ga(C 5H 5) has also been shown to serve as a cyclopentadienyl transfer reagent as it reacts with FeCl 2 to form Fe(C 5H 5) 2 and Me 2GaCl.
