Triptycene Boronates, Boranes, and Boron Ate‐Complexes: Toward Sterically Hindered Triarylboranes and Trifluoroborates

xloma.fota13 shared this article with you from Inoreader Triptycene Boronates, Boranes, and Boron Ate‐Complexes: Toward Sterically Hindered Triarylboranes and Trifluoroborates Via European Journal of Organic Chemistry Two synthetic strategies towards bulky boranes, boronates and boron ate‐complexes derived from triptycenes have been developed. These approaches started from borylated or brominated anthracenes and involved a Br/Li exchange and [4+2] cycloaddition reaction with in‐situ generated benzyne to produce a series of triptycene boronates and borates substituted in positions 1 or 9 with various boron substituents such as BPin, Bneo, BF 3 K and B(Mes) 2 . X‐ray diffraction crystallographic analysis and UV‐Vis/fluorimetric measurements provided quantitative information on the effect of the triptycene scaffold on their structure and their photophysical and electronic properties.
