Biaryl-substituted unsymmetrical diarsanes: transformation into As-stereogenic Buchwald-type ligands
Chihiro Okochi, Akifumi Sumida, Yusuke Miyake, Takahiro Iwamoto, Kensuke Naka, Hiroaki ImotoUnsymmetrical biaryl diarsanes were synthesized from dithiaarsoles. Oxidative As–As bond cleavage afforded As-stereogenic arsa-Buchwald ligands, demonstrating diarsanes as versatile chiral ligand precursors.
