Key Points

To develop a method for Markovnikov-selective hydroboration of unactivated alkenes using dual catalysis.
Employ Markovnikov-selective hydroboration using MHAT
Utilize cobalt and photoredox dual catalysis
Investigate the reaction across mono-, di-, and trisubstituted alkenes

Abstract

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.
