Isothiouronyl radical cations have been identified as a new class of radical catalysts for the covalent activation of vinylcyclopropanes. Their generation by photoredox catalysis from N,N,N,N-tetrasubstituted thioureas provides a modular, versatile and practical platform to achieve covalent radical catalysis.
