In this study, the borylation of heteroarene boronate esters was achieved under very mild conditions in an easy-to-use gel nanoreactor, using visible light as the energy source at room temperature in photocatalyst-free and aerobic conditions. The gel network provided a stabilizing microenvironment to support a wide substrate scope, making this protocol attractive for the synthesis of new materials.
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 halides under very mild conditions in an easy-to-use gel nanoreactor. Its use of visible light as the energy source at room temperature in photocatalyst-free and aerobic conditions makes this protocol very attractive. The gel network provides an adequate stabilizing microenvironment to support wide substrate scope, including furan, thiophene, selenophene, and pyrrole boronate esters.
