Synthesis of three-dimensionally arranged bis-biphenol ligand on hexaaryl benzene scaffold and its application for cross-pinacol coupling reaction
摘要:
The three-dimensionally arranged bis-biphenol ligand on a hexaaryl benzene scaffold for a dinuclear complex was synthesized by the Diels-Alder addition-decarbonylation reaction as a key step. Its preliminary studies on the titanium-induced cross-pinacol coupling reaction were performed based on step-by-step activation of two different aldehydes. (C) 2011 Elsevier Ltd. All rights reserved.
