Abstract
AbstractA synergetic catalytic system of organophotocatalyst 4CzIPN, thianthrene, and methanol was developed for visible‐light‐induced Giese reactions of various alkanes and alkenes, upon using alkoxy radicals as hydrogen atom transfer reagents. The reaction can be performed under mild conditions to provide the alkylated products in moderate to excellent yields, avoiding the use of any strong oxidants and transition metal reagents. Different from the known LMCT and PCET processes, the key to success of this approach is the in situ thianthrenation of methanol by thianthrene radical cation to trigger the generation of methoxy radical.
