摘要：

The development of strategies to access boronate esters from ubiquitous aliphatic C-H bonds is of long-standing interest in the synthesis community.Here photoelectrochemically driven C(sp~3)-H borylation of alkanes is developed,in which iron,an abundant earth-based resource,is employed as a photoelectrochemical catalyst.Using this protocol,direct borylation of strong alkyl C-H bonds is efciently achieved at a low oxidation potential of ~0.3 V and mild conditions.A wide range of structurally diverse alkyl boronic esters,including versatile α-silyl boronic esters,can be accessed with good regioselectivity.
