A visible light photocatalytic cleavage of trityl thioethers or ethers under pH-neutral conditions provides symmetrical disulfides and alcohols in good yield. The protocol only requires the addition of a suitable photocatalyst and light rendering it orthogonal to several functionalities, including acid labile protective groups.
