Borylation of Arenes with Bis(hexylene glycolato)diboron
摘要:
A series of diolate-substituted diboron compounds were investigated as reagents for iridium-catalyzed C-H borylations of arenes. These studies showed that commercially available bis(hexylene glycolato)diboron reacts with arenes in the presence of the catalyst generated from [Ir(COD)OMe](2) and di-tert-butylbipyridine. This reagent is prepared from a less expensive diol than the more commonly used bis(pinacolato)diboron reagent.

Heteroarene boronate esters constitute valuable intermediates in modern organic synthesis. As building blocks, they can be further applied to the synthesis of new materials, since they can be easily transformed into any other functional group. Efforts toward novel and efficient strategies for their preparation are clearly desirable. Here, we have achieved the borylation of commercially available heteroarene
