In the presence of a thiylradical species, the catalytic Markovnikov thiol–ene reaction is challenging because it prefers to proceed via a radical pathway, thereby leading to anti-Markovnikov selectivity. In this work, a rare example of thiylradical engaged in Markovnikov thiol–ene reaction enabled by cobalt catalysis is reported. This protocol features the avoidance of unique oxidants, exclusive
Hydridopalladium(II) species generated in situ by oxidative addition of Pd(0) to acetic acid or acidic hydroxyl substrates (phenols, oximes) catalyse the termolecular assembly of allenes, CO and amines (primary, secondary) or oxygen nucleophiles to give methacrylamides or methacrylate esters and derivatives thereof in good to excellent yield.
