Markovnikov-Selective Hydroboration of Unactivated Alkenes via MHAT under Cobalt/Photoredox Dual Catalysis

Catalytic Markovnikov-selective hydroboration of unactivated alkenes is a powerful tool for accessing alkyl boronic esters. Here, we report Markovnikov-selective MHAT hydroboration of unactivated alkenes enabled by cobalt/photoredox dual catalysis. The reaction proceeded via radical intermediates, providing high regioselectivity with mono-, di-, and trisubstituted alkenes.
