Abstract
Alkyl halides are readily available starting materials for various synthetic transformations,
including Minisci-type C–H functionalizations of hetarenes. The existing methods,
however, often require harsh reaction conditions, such as the use of acids, sacrificial
electron donors, or radical precursors in excess amounts. Here, we outline recent
developments in this field and we highlight our group̓s efforts to achieve fully catalytic
photoredox Minisci-type alkylations supported by noncovalent interactions under mild
aqueous conditions.
