The study investigates the impact of cationic micelles, specifically hexadecyltrimethylammonium bromide (CTABr), on the acidity of carbon acids and phenols, as well as the electronic and 'H nuclear magnetic resonance (NMR) spectral characteristics of nitro carbanions in micelles. The researchers found that CTABr micelles significantly enhance the acid dissociation of various carbon acids and phenols, with the effect being most pronounced for nitro carbanions. The study involved several chemicals, including 4-nitrophenylacetonitriles, 1-nitroindene, 4-nitrophenol, and 2,6-di-tert-butyl-4-nitrophenol, which were used to examine the changes in their acid dissociation constants (pKa values) in the presence of CTABr micelles. Additionally, the visible and 'H NMR spectra of these nitro carbanions were analyzed to understand the interactions between the carbanions and CTABr molecules. The results showed that CTABr micelles cause a red shift in the visible spectra of nitro carbanions and induce upfield shifts in the 'H NMR signals of the aromatic protons of the carbanions and the N+(CH3)3 protons of the surfactant, indicating tight interactions. The study concludes that the presence of CTABr micelles enhances the acidity of carbon acids and phenols by stabilizing the anionic form through tight association with the surfactant molecules, and the spectral changes observed are attributed to the unique interactions within the micelle environment rather than chemical reactions.
The study presents an environmentally benign and operationally simple method for the regio- and stereoselective synthesis of (Z)-3-methyleneisoindolinones in an aqueous micellar medium. The key chemicals involved include 2-iodo-N-phenyl-benzamides and terminal alkynes as starting materials. The reaction is catalyzed by Pd(CH3CN)Cl2 in the presence of 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene as a ligand, and cetyltrimethylammonium bromide (CTAB) as a surfactant to form micelles, which enhance the solubility and reaction efficiency. The use of DBU as a base is crucial for achieving high yields. This Cu-free domino Sonogashira reaction followed by 5-exo-dig cyclization under aerobic conditions allows for the synthesis of a library of (Z)-3-methyleneisoindolinones with high yields and short reaction times, highlighting the eco-friendly and efficient nature of the protocol.
The study investigates the light-triggered complexation of dioxygen by Co(II)-meso-tetraphenylporphyrin (Co"TPP) and its long-chain derivatives in aqueous micellar solutions. The researchers used Triton X-100, sodium dodecyl sulfate (SDS), and cetyltrimethylammonium bromide (CTAB) as the micelles. The study found that the complexation of dioxygen is induced by irradiation in the Soret band or the visible absorption band, and it is reversible at room temperature even in dilute detergent solutions. The initial binding of an ether oxygen of Triton or a water molecule to the cobalt atom is proposed as the first step, with visible irradiation ejecting one of these ligands to allow dioxygen to bind. The stability and reversibility of these systems are shown to be highly sensitive to the structure and environment of the metalloporphyrins, with the liquid interface playing a crucial role. The study provides quantum yields for the photo-processes and thermodynamic data for ionic and non-ionic micellar solutions, suggesting that these simple models can meet most conditions required for cobalt-reconstituted biological dioxygen carriers to function similarly to natural carriers.
