Asymmetric catalytic Mannich-type reaction of hydrazones with difluoroenoxysilanes using imidazoline-anchored phosphine ligand-zinc(II) complexes.

ABSTRACT: Asymmetric Mannich-type reaction of hydrazones with difluoroenoxysilanes using chiral zinc(II)-imidazoline-phosphine complexes as catalysts have been established, giving the corresponding adducts in good to excellent enantioselectivity and chemical yields under mild conditions.
