Photocatalytic carbon–carbon bond formation with concurrent hydrogen evolution on colloidal zinc sulphide

In the photocatalytic system containing colloidal ZnS, water, and organic substrates such as triethylamine, tetrahydrofuran, or methanol, oxidative carbon–carbon bond formation occurs with efficient reductive H2 evolution, to give the dimeric products 2,3-bis(diethylamino)butane, 2,2′-bitetrahydrofuryl, or ethylene glycol, respectively.
