1,1-Diaryl moieties are core structures in a wide range of bioactive and pharmaceutical compounds.Transition-metal catalysis is a convenient approach to accessing these invaluable compounds affording high yields and enantioselectivities.This review summarizes 1,1-diarylalkanes synthesis through transition metal catalysis.Particular focus is given to recent developments,such as reductive cross-electrophile couplings,benzylic C-H bond arylation,transformations involving metal migration,asymmetric hydrogenation of 1,1-diarylalkenes and three-component coupling reactions.
