Usage

General Description

4-Tert-Butylbenzophenone, also known as 4-tert-Butyl-4'-methoxydibenzoylmethane, is a chemical compound commonly used as a UV filter in sunscreens and other cosmetic products. It works by absorbing, reflecting, or scattering harmful UV radiation to protect the skin from sun damage. 4-TERT-BUTYLBENZOPHENONE is also used in the production of plastics, adhesives, and other industrial applications. 4-Tert-Butylbenzophenone is known to have antioxidant and photostabilizing properties, making it a valuable ingredient in a wide range of products. However, there are potential concerns about its impact on the environment and human health, and further research is needed to fully understand its safety and potential risks.

Designing highly fluorescent, arylated poly(phenylene vinylene)s of intrinsic microporosity

Three new polymers containing tetraphenylethylene and diphenyl-dinaphthylethylene cores and their corresponding monomeric model compounds were synthesized and fully characterized aiming to investigate their photoluminescence efficiency, microporosity and Brunauer-Emmett-Teller-derived surface areas (SBET). Comprehensive photophysical characterization was undertaken in the solid state (powder and thin films), in tetrahydrofuran (THF) solution and in mixtures of "good" and "poor" solvent to induce aggregation (THF:water mixtures). Aggregation induced emission (AIE) was found for the tert-butyl-TPE monomer and polymer and diphenyl-dinaphthylethylene monomer with the increase of the water amount in THF:water mixtures and in the solid state. The tert-butyl substituted TPE derivatives display the highest fluorescence quantum yield (?F) values: 0.14 to 0.30 (in powder) and 0.46 to 0.64 in thin films. In contrast, with the diphenyl-dinaphthylethylene (meta and para-phenylene) polymers aggregation caused quenching (ACQ) occurs in THF:water mixtures (?F ≤ 0.011) and in the solid state (?F ≤ 0.012). The microporosity of the soluble conjugated polymers as potential conjugated polymers of intrinsic microporosity (cPIMs) was further investigated. The SBET of the polymers were related to their optical properties. The polymers show an attractive combination of high SBET surface area (417 m2 g-1) and the occurrence of distinct AIE effects for the tert-butyl-TPE polymer while the diphenyl-dinaphthylethylene polymers do not exhibit microporosity (SBET ≤ 17 m2 g-1) and show ACQ behavior.

Generation of Aryllithium Reagents from N -Arylpyrroles Using Lithium

Treatment of 1-aryl-2,5-diphenylpyrroles with lithium powder in tetrahydrofuran at 0 °C results in the generation of the corresponding aryllithium reagents through reductive C-N bond cleavage.

Palladium-Catalyzed Amide N-C Hiyama Cross-Coupling: Synthesis of Ketones

N-Acylglutarimides and arylsiloxanes reacted in the presence of Pd(OAc)2/PCy3, Et3N·3HF, and LiOAc to provide the corresponding arylketones in good yields. Aryl-, vinyl-, and alkyl-substituted N-acylglutarimides showed good activity in the coupling reactions of arylsiloxanes. The reaction had a broad substrate scope and showed good functional group tolerance. N-Benzoylsuccinimide and N-protected N-phenylbenzamides showed good activities in coupling reactions with phenylsiloxane. The employment of CuF2 as an activor afforded the decarbonylative products at 160 °C.
