Alkyl boronic acids and esters play an important role in the synthesis of C(sp3)-rich medicines, agrochemicals, and material chemistry. This work describes a new type of transition-metal-free mediated transformation to enable the construction of C(sp3)-rich and sterically hindered alkyl boron reagents in a practical and modular manner. The broad generality and functional group tolerance of this method

C(sp2)-C(sp3) cross-coupling of these fragments to afford biaryl isosteres have been scarce. Herein we describe the development of continuous flow-enabled synthesis of bench-stable bicyclo[1.1.1]pentane trifluoroborate salts. Furthermore, we demonstrate the use of metallaphotoredox conditions to enable cross-coupling of these building blocks with complex arylhalide substrates.
