Organoboron compounds are important building blocks in organic synthesis and have been widely applied in materials and pharmaceutical science. The development of practical and concise borylation reactions to synthesize organoboron compounds has always been one of the core topics of organoboron chemistry. Recently, photochemical and electrochemical borylation reactions have gained rapid development and emerged as important methods towards the synthesis of organoboron compounds. The recent research progress concerning photochemical, electrochemical and photoelectrochemical borylation involving aryl and alkyl compounds from the view of energy resources and substrates is reviewed. Additionally, research trends of this area are also discussed.

Key words: photochemistry, electrochemistry, photoelectrochemistry, borylation, organoboron compound
