polarized alkyl tosylate C—O bonds to the fairly limited number of C—O bonds able to participate in free radical cleavage pathways. The mechanistic studies suggested that in situ‐generated silver(0) catalytic species were the active catalytic species and played a key role in the radical pathway cleavage of C—O bonds.
