WITHDRAWN: Asymmetric Ni-catalyzed arylation of aromatic aldehydes with arylboroxines

The publisher regrets that this was an accidental duplication of an article that has already been published in Tetrahedron Lett. 48 (2007) 4115-4117, doi:10.1016/j.tetlet.2007.04.025. The duplicate article has therefore been withdrawn.
