Boron-doped TiO2(B-TiO2) was prepared, characterized, and successfully applied as a reusable, inexpensive, available, and heterogeneous nanophotocatalyst under visible light for a novel method of construction of phenacyl thiocyanate compounds from double or triple bonds. Impressive aspects of this project are obtaining the desired compounds in a short time, using a renewable energy source, and using a catalyst with easy extraction that is solvent-safe, and without the use of any oxidants, bases, and ligands, or harsh conditions. This is the first report of the construction of phenacyl thiocyanates through this photocatalytic method under visible light.

A novel visible light-driven oxidative cascade reaction for the synthesis of β-thiocyanato alcohols via difunctionalization of alkenes is described for the first time. In this protocol inorganic ion thiocyanate was successfully converted into radical through photocatalysis by employing Rose Bengal as a photocatalyst to mediate the single-electron transfer. This hydroxylation process did not need extra reducing agent and the new C–S and C–O bonds could be constructed in one pot. Molecular oxygen not only was used as an excellent terminal oxidant, but also served as a green oxygen source, which is one of the most ideal processes to realize C–H bond oxidation functionalization. Moreover, the reaction also proceeded very well under irradiation of sunlight.

A number of epoxides smoothly react with TPPT under mild conditions to give α-thiocyanatovinyl ketones, vic-dithiocyanates, or vic-thiocyanatohydrins, depending on the structures of the epoxides used.The reactions proceed site- and stereo-specifically, to give α-thiocyanatovinyl ketones from αβ-epoxyketones, threo-dithiocyanate from trans-epoxide, erythro-dithiocyanate from cis-epoxide, and vic-thiocyanatohydrins from 1,1-disubstituted or fused epoxides, respectively.A possible mechanism for these reactions is put forward.
