Boron-doped TiO2 (B-TiO2): visible-light photocatalytic difunctionalization of alkenes and alkynes

Abstract

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.
