Crystal structure of 4-(4-methoxyphenoxy)benzaldehyde
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C14H12O3, was synthesized via the nucleophilic addition of 4-methoxyphenol to 4-fluorobenzaldehyde. The dihedral angle between the least-squares planes of the benzene rings is 71.52 (3)° and the C—O—C angle at the central O atom is ...

An investigation of the roles furan versus thiophene π-bridges play in donor–π-acceptor porphyrin based DSSCs [PDF]
, 2018 Dye-sensitized solar cells (DSSCs) continue to attract interest due to their lower cost production compared to silicon based solar cells and their improving power conversion efficiencies. Porphyrin-based sensitizers have become an important sub-class due

Advanced Science, EarlyView.The research reveals that polysulfide anions (K2Sx), which serve as reducing catalysts, can also effectively act as sulfur reagents, providing the formation of C(sp3)─S bonds through photoredox catalysis with an oxidative photocatalyst tetrabutylammonium decatungstate (TBADT) and dual hydrogen atom transfer (DHAT) process.

Catalytic 1,2‐Migratory Insertion in a Bismuth Redox Platform: Reductive Arylation of Aldehydes
Angewandte Chemie, EarlyView.We report a multicomponent reaction involving an aryl halide, an aldehyde, and a silane derivative, facilitated by low‐valent bismuth redox catalysis under mild conditions. The protocol represents an unprecedented example of four elementary organometallic steps at a Bi center within the catalytic cycle.

Advanced Science, EarlyView.In this work, an electrochemical strategy employing hydroperoxyl radicals and a molybdenum‐based catalyst (Mo─N─O) enables selective double‐bond oxidation in cinnamaldehyde, preserving aldehyde integrity. Under mild, energy‐efficient conditions (−200 mA), this approach converts cinnamaldehyde to benzaldehyde with complete conversion (100%) and >99 ...

Oxidation of benzaldehyde in some single phase betaine-benzaldehyde-water systems
Journal of Pharmacy and Pharmacology, 1964 AbstractThe oxidation rates of increasing concentrations of benzaldehyde in ternary systems of the L1 type have been measured in aqueous solutions of four betaine homologues. On applying corrections for extra-micellar material, the rate becomes independent of the betaine concentration and is related to the micellar ratio of benzaldehyde to betaine when

High turnover in electro-oxidation of alcohols and ethers with a glassy carbon-supported phenanthroimidazole mediator. [PDF]
, 2017 Glassy carbon electrodes covalently modified with a phenanthroimidazole mediator promote electrochemical alcohol and ether oxidation: three orders of magnitude increase in TON, to ∼15 000 in each case, was observed compared with homogeneous mediated ...
