Lastly, desulfurative borylation to yield alkylboronic esters was assessed using either a sacrificial Mg anode (conditions J) or a graphite anode in presence of NBu 4 BH 4 (conditions K). For this cross-coupling protocol, good to excellent yields of the corresponding borylated products from a selection of benzylic and allylic phenyl thioethers were obtained using either set of conditions (Figure , top right), clearly demonstrating the complementary nature of the two anodic counter reaction strategies. Control experiments for conditions K revealed that compound 5a did not form in the absence of current and in mere 9% with NBu 4 Br in absence of NBu 4 BH 4 , confirming that both electricity and borohydride reagents are required for successful reaction outcome.
