Substituent effects on the Lewis acidity of 4,6-di-tert-butylchatechol boronate esters

, p. 31 - 35 (2019)
In studying the factors which contribute to the Lewis acidity of organoboron compounds we investigated approaches to the design of robust, novel Lewis acids purposed for metal-free catalysis. Based on a sterically encumbered catechol motif, a series of boronate esters are shown to demonstrate modest Lewis acidities for the conventional Gutmann-Beckett test as an inquisitive investigation.
Five-coordinate MII-semiquinonate (M = Fe, Mn, Co) complexes: Reactivity models of the catechol dioxygenases

A series of five-coordinate MII-semiquinonate (M = Fe, Mn, Co) complexes were synthesized and characterized, including the first example of a mononuclear FeII-semiquinonate. Intermediates were observed in the reactions of MII-phenSQ (M = Fe, Co) with O2. Evidence for the relevance of these intermediates to the intradiol catechol dioxygenases was obtained by characterization of the oxidized semiquinone-derived product, muconic anhydride, resulting from the reaction of [PhTttBu]Co II(3,5-DBSQ) with O2. This journal is the Partner Organisations 2014.
