4-Trifluoromethylbenzyl bromide is a choline derivative that acts as an anticancer agent. It is structurally similar to the anticancer drug doxorubicin, which has been shown to be effective against breast cancer and leukemia. 4-Trifluoromethylbenzyl bromide interacts with cellular proteins, including choline kinase, and inhibits the mitochondrial pathway. This leads to cell death through apoptosis. The molecule also interacts with nucleotide bases such as thymine and cytosine in DNA, inhibiting transcription and replication. 4-Trifluoromethylbenzyl bromide binds strongly to the hydroxyl group of cholesterol by an electrophilic substitution mechanism to form a covalent bond with its hydroxy group. The molecule can also bind to chloride ions by an ionic bond., 402-49-3.

Yang, Xiaoxu;Ge, Shaozhong research published 《 Cobalt-Catalyzed 1,1,3-Triborylation of Terminal Alkynes》, the research content is summarized as follows. The authors have developed a Co-catalyzed regioselective 1,1,3-triborylation reaction of terminal alkynes with pinacolborane (HBpin) with a catalyst generated in situ from readily available and bench-stable Co(acac)₂ and xantphos. A variety of terminal alkynes undergo this triborylation reaction, affording the corresponding 1,1,3-triborylalkanes in good yields with high selectivity. The synthetic utility of this catalytic protocol was demonstrated by developing selective stepwise functionalization of 1,1,3-triborylalkane products. The results of mechanistic studies, such as conducting control experiments and D-labeling reactions, monitoring the reaction process, and identifying reaction intermediates, suggest that this 1,1,3-triborylation reaction proceeds through 1,3-diborylation of alken-1-ylboronates formed by Co-catalyzed hydroboration of terminal alkynes.

3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., Name: 3,5-Dibromo-2-hydroxybenzaldehyde

The present work addresses this issue by designing an asym. allylation/ring expansion reaction of 2-(1-hydroxyallyl)phenols and cyclobutanone carboxamides enabled by sequential iridium/zinc/bifunctional squaramide catalysis, affording a series of 8-membered benzo[b]oxocines in high yields with high diastereo- and enantioselectivities. Mechanistic investigation revealed that the enantioselectivity was controlled by the chiral iridium catalyst, while d. functional theory calculations demonstrate that the diastereoselectivity was controlled by the chiral bifunctional squaramide catalyst. Moreover, the sequential allylation reaction strategy was demonstrated to be also applicable to the synthesis of two types of enantiomerically enriched nitrogen heterocycles, 8-membered benzo[b]azocines and polycyclic cyclobuta[b]quinolines.

And the article contained the following:

We report the syntheses, structures, photophys. properties, and redox characteristics of the [2+2] pyromellitic diimide-based macrocycle with a linear π-electronic system 2 as well as the 3,6-bis(phenylethynyl)pyromellitic diimide derivative 3. The interesting solid state structural properties of the clathrates of 3 with π-donors are also reported. The macrocycle 2 was synthesized by the direct cyclocondensation followed by the Sonogashira coupling reaction. X-ray crystallog. studies showed that the phenylacetylene moieties in 2 formed the intramol. benzene dimer structures, and the bis(phenylethynyl)pyromellitic diimide moieties in both 2 and 3 were stacked in a parallel and slanted arrangement. Theor. calculations for 2′ and 3 suggested the existence of electrostatic interactions between the bis(phenylethynyl)pyromellitic diimide moieties. The UV/vis spectral measurements and TDDFT calculations of 2, 2′, and/or 3 were performed to understand their electronic transitions. The fluorescence spectral measurements showed that 2 and 3 have visible fluorescence properties and 2 displays an excimer fluorescence at ca. 590 nm. The cyclic voltammetry measurements revealed that the electrostatic repulsion between the diimide moieties in 2 is greater than that in 1 according to the extension of the π-electronic systems. X-ray crystallog. of the clathrates of 3 with various π-donors demonstrated the formation of the segregated donor-acceptor structures, indicating the strong aggregation ability of the bis(phenylethynyl)pyromellitic diimide moiety.
