Coordination Networks Based on Boronate and Benzoxaborolate Ligands

open access: yesCrystals, 2016
Despite the extensive range of investigations on boronic acids (R-B(OH)2), some aspects of their reactivity still need to be explored. This is the case for the coordination chemistry of boronate anions (R-B(OH)3−), which has only recently been started to

Synthesis of Meso‐Substituted Subphthalocyanine–Subporphyrin Hybrids: Boron Subtribenzodiazaporphyrins [PDF]

open access: yes, 2015
The first syntheses of hybrid structures that lie between SubPhthalocyanines and SubPorphyrins are reported. The versatile, single-step synthetic protocol uses a preformed aminoisoindolene to provide the bridging methine unit and its substituent, while ...

Aryl nitrile oxide cycloaddition reactions in the presence of pinacol boronic acid ester

open access: yesBeilstein Journal of Organic Chemistry, 2012
An aryl substrate with dual functionality consisting of a nitrile oxide and a pinacolyl boronate ester was prepared by mild hypervalent iodine oxidation (diacetoxyiodobenzene) of the corresponding aldoxime, without decomposition of the boronate ...
