Decarboxylative Xanthylation under Photocatalytic Conditions

Xanthates are widely used in organic synthesis for the construction of various molecules and have numerous applications as bioactive compounds. Here, we present their preparation via a straightforward photocatalytic decarboxylative xanthylation process involving readily available oxime esters and xanthate dimers. This approach provides access to a wide variety of xanthate compounds in moderate to good yields, including xanthates derived from relevant pharmaceutical and bioactive molecules.
