In 2020, the Aggarwal group reported the first case of metal-free photoinduced borylation of alkanes (Scheme 1b), due to the low reactivity of alkanes, the reaction requires high equivalency of alkane substrates (10 equiv.), and the yields based on diboron are relatively low (lower than 50% in most cases). Given that boronic esters are important in organic synthesis and medicinal chemistry, it is of great significance to develop substrate equivalent and efficient C-H borylation methods.
