Synthesis of phosphine substituted beta-diketiminate based isomeric Ge(II) complexes.
Treatment of phosphine substituted beta-diketiminate lithium, Ph2PC[C(Me)N(Dipp)]2LiOEt2 (1) (Dipp = 2,6-iPr2C6H3) with dioxane x GeCl2 resulted in a five-membered N,P chelate complex, Ph2PC[C(Me)N(Dipp)]2GeCl (2). An isomer of 2 CH{[C(CH2PPh2)N(Dipp)][C(Me)N(Dipp)]}GeCl (5) was obtained from the germanium complex L'Ge (L' = CH[C(CH2)N(Dipp)][C(Me)N(Dipp)])Ge (4) and Ph2PCl. In 5 the PPh2 group remains uncoordinated. Both complexes were characterized by X-ray structural analysis and in the case of 5 both enantiomers crystallize in the same unit cell.
