Research Abstract |
We have developed new chiral diene ligands base on tetrafluorobenzobarrelene(tfb) framework. Their rhodium complexes displayed high catalytic activity and enantioselectivity in the addition of arylboron reagents to unsaturated bonds. Iridium/chiral tfb complexes were also found to display high catalytic activity in the asymmetric 1, 6-addition of arylboroxines to dienones giving the corresponding addition products in high yields with high enantioselectivity.
