A Water-Stable Boronate Ester Cage
The reversible condensation of catechols and boronic acids to boronate esters is a paradigm reaction in dynamic covalent chemistry. However, facile backward hydrolysis is detrimental for stability and has so far prevented applications for boronate-based ...

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

Coordination Networks Based on Boronate and Benzoxaborolate Ligands
Crystals, 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

Formation of C(sp(2))-Boronate Esters by Borylative Cyclization of Alkynes Using BCl3 [PDF]
, 2015 BCl3 is an inexpensive electrophile which induces the borylative cyclization of a wide range of substituted alkynes to regioselectively form polycycles containing synthetically versatile C(sp2)boronate esters. It proceeds rapidly, with good yields and is

Boron-Based (Nano-)Materials: Fundamentals and Applications
Crystals, 2016 The boron (Z = 5) element is unique. Boron-based (nano-)materials are equally unique. Accordingly, the present special issue is dedicated to crystalline boron-based (nano-)materials and gathers a series of nine review and research articles dealing with ...

Synthesis of Boron Analogues of Enamines via Hydroamination of a Boron−Boron Triple Bond [PDF]
Angewandte Chemie International Edition, 2020 AbstractAn N‐heterocyclic‐carbene‐stabilized diboryne undergoes rapid, high‐yielding and catalyst‐free hydroamination reactions with primary amines, yielding 1‐amino‐2‐hydrodiborenes, which can be considered boron analogues of enamines. The electronics of the organic substituent at nitrogen influence the structure and further reactivity of the diborene
