Database of Photocatalytic Dehydrogenation Reactions

This database contains a summary of photocatalytic reactions in which organic transformations are coupled with the production of hydrogen (H2). The database contains 236 entries that were collected from 216 articles published between 1982-2023. The database contains the following information. 1) Source article bibliographic data (first author(s), corresponding author(s), corresponding author(s) affiliation country(ies), article DOI, publication year). 2) Reaction classification according to the type of bond formation (such as C-B, C-C, C-H, C-N, C-O, C-P, C-S, C-Si, S-S, Si-O, N-N); hybridization of carbon atoms involved in the formation of the chemical bond (sp3-, sp2, sp-); cross-coupling (synthesis of a product from two or more reagents) vs. homo-coupling (di- and oligomerization of the reagent); intramolecular cyclization vs. intermolecular cyclization; extent of reagent dehydrogenation (loss of one, two or more H2 molecules). 3) Type of the photocatalyst (homogeneous, heterogeneous), its chemical structure and the amount (moles, grams) used in the reactions. 4) Redox potentials of the photocatalyst excited state (V vs. reference electrode). 5) Type, chemical structure and amount of the H2-evolution catalyst. 6) Assembly of the photocatalyst and H2-evolution catalyst (such as direct mixing in the photoreactor, photochemical reduction of H2-evolution catalyst precursor at the photocatalyst, chemical reduction of H2-evolution catalyst precursor at the photocatalyst, solvothermal growth of H2-evolution catalyst at the photocatalyst, etc.). 7) Type, chemical structure and amount of the organocatalyst, hydrogen atom transfer (HAT) catalyst and/or additive(s). 8) Type of light source (such as LED, Xe-lamp, Hg-lamp, etc.), electric power (W), emission wavelength maximum (nm), light intensity (W cm-2). 9) Quantum yield of the reaction (% at the specific wavelength). 10) Solvent and its volume (mL). 11) Chemical structure, amount (moles, grams) and concentration of the reagent(s) (mol L-1). 12) Reaction time (h). 13) Batch or flow mode of the reaction. 14) Chemical structure, yield and yield rate (in mol g[catalyst]-1 h-1) of the major product. 15) Yield and yield rate of hydrogen.
