In 2022,Musza, Katalin; Meszaros, Rebeka; Baan, Kornelia; Konya, Zoltan; Kukovecz, Akos; Palinko, Istvan; Sipos, Pal; Szabados, Marton published an article in Journal of Molecular Structure. The title of the article was 《Mechanochemical preparation of NiCuSn nanoparticles and composites in presence of cetyltrimethylammonium bromide (CTAB) and the catalytic application of the products in homocoupling and hydration of terminal alkynes》.Related Products of 516-12-1 The author mentioned the following in the article:
The synthesis of the NiCuSn nanoparticles and nanocomposites in mechanochem. route using CTAB as milling additive was reported. The study of grinding intensity (frequency) and time interval drew up the importance of the well-chosen operation parameters. The mild milling resulted in formation of NiSn intermetallics, while the intense ones aided the evolution of bronze and copper(I) oxide phases. The utilization of CTAB proved to be the key factor to prevent or slow down the process of mech. alloying and to fritter the metal grains into the nanodimensions. The dynamic light scattering data demonstrated pos. charged particles with average solvodynamic diameters of around 70 nm applying intense or long-term millings. Without CTAB or with relatively short or weak grindings, these values remained between 230 and 550 nm, as in the case of the surface areas getting around 20 m2/g with and 1 m2/g without CTAB. The catalytic transformation of p-methoxyphenylacetylene in DMSO showed that the copper, copper(I) oxide and bronze particles managed the reaction toward the evolution of 1,3-diyne in Glaser-Hay homocoupling without base addition, while the Sn and SnO2 phases assisted to the Markovnikov-type hydration of alkyne groups. The formation of α-diketone signed that the anti-Markovnikov route was also occurred. The use of CTAB was found to exert a profound effect on the quality of catalytic end-products through the controlled generation of bronze and tin oxide phases and the solid solution of nickel atoms. In the part of experimental materials, we found many familiar compounds, such as 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Related Products of 516-12-1)
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
