LIGAND REDISTRIBUTION REACTIONS OF ME2GA(C5H5) AND MEGA(C5H5)2

The compounds Me2Ga(C5H5) and MeGa(C5H5)2 have been prepared by ligand redistribution reactions between appropriate stoichiometric quantities of Ga(C5H5) and GaMe3. Both compounds have been demonstrated by H-1 NMR spectral studies to be unstable in solution and to form symmetrized products by ligand redistribution reactions. Thus, Me2Ga(C5H5) forms GaMe3 and MeGa(C5H5)2 as primary products whereas MeGa(C5H5)2 decomposes to Ga(C5H5)3 and Me2Ga(C5H5). The compound Me2Ga(C5H5) has also been shown to serve as a cyclopentadienyl transfer reagent as it reacts with FeCl2 to form Fe(C5H5)2 and Me2GaCl.
