A boron trifluoride catalysed reaction of coplanar 9-(phenyl-ethynyl)-9 H-fluoren-9-ols with various 2-aminobenzamides affords a number of highly functionalized, conjugated (Z)-2-((2-(9 H-fluoren-9-ylidene)-1-phenylethylidene)amino) benzamides in excellent yield. The reaction in the presence of N-bromosuccinimide affords (E)-5-bromo-2-((2-bromo-2-(9 H-fluoren-9-ylidene)-1-phenylethylidene)amino)benz-amides in very good yields. The scope of the reaction is demonstrated by selecting N-aryl substituted 2-aminobenzamides and aminosulfonamides as reaction partners. The structures of representative compounds were established by single-crystal XRD analysis. Based on the structure of the products, a plausible mechanism via formation of allene carbocation intermediates is proposed.

Labeling of heterocycles with carbon-11 is generally performed through peripheral functionalizations and more scarcely inside heterocyclic core. Such less common approach usually requires preliminary multi-step synthesis of reactive species. Herein, a cyclization reaction by direct use of cyclotron-produced [C-11]CO2 is described to obtain various heterocycles intracyclically labeled in only 10 minutes.

Recommanded Product: Benzophenone. I found the field of Pharmacology & Pharmacy; Chemistry; Toxicology very interesting. Saw the article Benzophenone Accumulates over Time from the Degradation of Octocrylene in Commercial Sunscreen Products published in 2021.0, Reprint Addresses Downs, CA (corresponding author), Sorbonne Univ, CNRS, Lab Biodiversite & Biotechnol Microbiennes, USR3579,Observ Oceanol, F-66650 Banyuls Sur Mer, France.; Downs, CA (corresponding author), Haereticus Environm Lab, Clifford, VA 24533 USA.. The CAS is 119-61-9. Through research, I have a further understanding and discovery of Benzophenone.

Benzophenone is a mutagen, carcinogen, and endocrine disruptor. Its presence in food products or food packaging is banned in the United States. Under California Proposition 65, there is no safe harbor for benzophenone in any personal care products, including sunscreens, anti-aging creams, and moisturizers. The purpose of this study was to determine (1) if benzophenone was present in a wide variety of commercial sun protection factor (SPF)/sunscreen products, (2) whether benzophenone concentration in the product increased over time, and (3) if the degradation of octocrylene was the likely source for benzophenone contamination. Benzophenone concentration was assayed in nine commercial sunscreen products from the European Union and eight from the United States (in triplicate), including two single ingredient sources of octocrylene. These same SPF items were subjected to the United States Food and Drug Administration (U.S. FDA)-accelerated stability aging protocol for 6 weeks. Benzophenone was measured in the accelerated-aged products. Sixteen octocrylene-containing product lines that were recently purchased had an average concentration of 39 mg/kg benzophenone, ranging from 6 mg/kg to 186 mg/kg. Benzophenone was not detectable in the product that did not contain octocrylene. After subjecting the 17 products to the U.S. FDA-accelerated stability method, the 16 octocrylene-containing products had an average concentration of 75 mg/kg, ranging from 9.8 mg/kg to 435 mg/kg. Benzophenone was not detectable in the product that did not contain octocrylene. Benzophenone was detected in the pure octocrylene manufactured ingredient. Octocrylene generates benzophenone through a retro-aldol condensation. In vivo, up to 70% of the benzophenone in these sunscreen products may be absorbed through the skin. U.S. FDA has established a zero tolerance for benzophenone as a food additive. In the United States, there were 2999 SPF products containing octocrylene in 2019. The safety of octocrylene as a benzophenone generator in SPF or any consumer products should be expeditiously reviewed by regulatory agencies.

A novel series of bis Indy-NHC gold complexes have been developed and investigated via a mild Agcarbene transfer route. The obtained complexes were characterized by NMR spectroscopy and X-ray diffraction analysis. The catalytic property of these gold complexes was further evaluated in the oxidation of benzylic. The gold complex E1 showed a high catalytic activity in the oxidation of various benzylic substrates, resulting in the corresponding carbonyl compounds with excellent yields using TBHP as oxidant.

Gas-phase C?C coupling reactions mediated by Ni (II) complexes were studied using a linear quadrupole ion trap mass spectrometer. Ternary nickel cationic carboxylate complexes, [(phen)Ni (OOCR1)](+) (where phen = 1,10-phenanthroline), were formed by electrospray ionization. Upon collision-induced dissociation (CID), they extrude CO2 forming the organometallic cation [(phen)Ni(R-1)](+), which undergoes gas-phase ion-molecule reactions (IMR) with acetate esters CH3COOR2 to yield the acetate complex [(phen)Ni (OOCCH3)](+) and a C?C coupling product R-1-R-2. These Ni(II)/phenanthroline-mediated coupling reactions can be performed with a variety of carbon substituents R-1 and R-2 (sp(3), sp(2), or aromatic), some of them functionalized. Reaction rates do not seem to be strongly dependent on the nature of the substituents, as sp(3)-sp(3) or sp(2)-sp(2) coupling reactions proceed rapidly. Experimental results are supported by density functional theory calculations, which provide insights into the energetics associated with the C?C bond coupling step.

A Cd(II) coordination polymer based on a polytopic compartmental ligand was synthesized, and used as an efficient heterogeneous catalyst for the Knoevenagel reaction between benzaldehyde and malononitrile under mild reaction conditions. The solid catalyst was characterized using single crystal XRD, X-ray powder diffraction, SEM, TGA, UV diffuse reflectance, infrared spectroscopy and elemental analysis. The compound is a two-dimensional (2D) MOF with a grid structure. Topological analysis of the framework revealed that it is a 2,4-connected binodal net. The catalytic activity was tested between various benzaldehydes containing different substituents with malononitrile. The effect of reaction parameters such as solvent, time, reactant ratio and catalyst amount was investigated. Furthermore, the catalyst stability was examined through reusability experiments and it is observed that the catalyst can be recycled at least five times without significant drop in its activity.

Organo-radical catalysts have recently attracted great interest, and the development of this field can be expected to broaden the applications of organocatalysis. Herein, the first example of a radical-generating system is reported that does not require any photoirradiation, radical initiators, or preactivated substrates. The oxidative C-C-bond cleavage of 2-substituted cyclohexanones was achieved using an azolium salt and a hydroquinone as co-catalysts. A catalytic mechanism was proposed based on the results of diffusion-ordered spectroscopy and cyclic voltammetry measurements, as well as computational studies.

In this research, a number of new and known chromenopyrano [2,3-b]pyridine derivatives have been prepared. Initially, according to the reported procedure, pyrano [2,3-c] chromene derivatives were synthesized by the reaction between 4-hydroxycoumarin, aromatic aldehydes and malononitrile using silica sodium carbonate (SSC) as the catalyst. Next, the prepared pyrano [2,3-c] chromenes were reacted by dimethyl acetylenedicarboxylate (DMAD) or cyclohexanone in the presence of sodium carbonate to produce chromenopyrano [2,3-b]pyridine derivatives. The presented protocol avoids the use of expensive catalysts and gives useful potentially bioactive heterocycles in excellent to high yields.
