Usage

General Description

1,4-Dibenzoylbenzene, also known as benzoylbenzene or dibenzoylbenzene, is a chemical compound with the molecular formula C20H14O2. It belongs to the class of organic compounds known as benzophenones, which are organic compounds containing a ketone attached to two phenyl groups. 1,4-Dibenzoylbenzene is a white to off-white crystalline powder that is insoluble in water but soluble in organic solvents. It is primarily used as a reactant in the synthesis of other organic compounds and as a component in the production of pharmaceuticals, dyes, and fragrances. Additionally, it has applications as an ultraviolet light absorber in sunscreen products. Although its exact toxicological properties are not well documented, it is generally considered to have low toxicity and is not expected to pose a significant risk to human health or the environment when used in accordance with proper handling and storage procedures.

Selective electrochemical oxidation of aromatic hydrocarbons and preparation of mono/multi-carbonyl compounds

A selective electrochemical oxidation was developed under mild condition. Various mono-carbonyl and multi-carbonyl compounds can be prepared from different aromatic hydrocarbons with moderate to excellent yield and selectivity by virtue of this electrochemical oxidation. The produced carbonyl compounds can be further transformed into α-ketoamides, homoallylic alcohols and oximes in a one-pot reaction. In particular, a series of α-ketoamides were prepared in a one-pot continuous electrolysis. Mechanistic studies showed that 2,2,2-trifluoroethan-1-ol (TFE) can interact with catalyst species and generate the corresponding hydrogen-bonding complex to enhance the electrochemical oxidation performance.

Pd-Catalysed carbonylative Suzuki-Miyaura cross-couplings using Fe(CO)5under mild conditions: generation of a highly active, recyclable and scalable ‘Pd-Fe’ nanocatalyst

The dual function and role of iron(0) pentacarbonyl [Fe(CO)5] has been identified in gaseous CO-free carbonylative Suzuki-Miyaura cross-couplings, in which Fe(CO)5supplied COin situ, leading to the propagation of catalytically active Pd-Fe nanoparticles. Compared with typical carbonylative reaction conditions, CO gas (at high pressures), specialised exogenous ligands and inert reaction conditions were avoided. Our developed reaction conditions are mild, do not require specialised CO high pressure equipment, and exhibit wide functional group tolerance, giving a library of biaryl ketones in good yields.

Ruthenium-Catalyzed Dehydrogenation of Alcohols with Carbodiimide via a Hydrogen Transfer Mechanism

Ruthenium-catalyzed oxidative dehydrogenation of alcohols using carbodiimide as an efficient hydrogen acceptor has been developed. The protocol exhibits wide substrate scope with good to excellent yields. The results of the kinetic analysis indicated that the reaction mechanism includes the hydrogen transfer process and that the addition of carbodiimide is essential for the reaction system, and the resulting amidine also could react as a hydrogen acceptor.
