《Black TiO2 nanoparticles with efficient photocatalytic activity under visible light at low temperature: regioselective C-N bond cleavage toward the synthesis of thioureas, sulfonamides, and propargylamines》 was written by Koohgard, Mehdi; Hosseini-Sarvari, Mona. HPLC of Formula: 98-60-2This research focused onthiourea sulfonamide propargylamine preparation regioselective photochem; tertiary amine carbon nitrogen bond cleavage black titanium dioxide; black titanium dioxide nanoparticle catalyst preparation. The article conveys some information:
Several different colored forms of TiO2 were prepared through the easy treatment of white TiO2 and NaBH4 as a safe hydrogen source. These types of modified TiO2 showed a quite acceptable visible light response. Then, tertiary amines were harnessed toward the regioselective synthesis of three prominent scaffolds, namely sulfonamides, thioureas, and propargylamines, using black TiO2 under visible light. For the first time, this type of modified TiO2 was easily prepared and exploited to handle organic transformations under visible light. Black TiO2-catalyzed oxidative C-N cleavage of tertiary amines was the key point of these transformations. Herein, the first report of the visible-light-driven synthesis of unsym. thioureas and propargylamines from tertiary amines has been presented. In the experiment, the researchers used many compounds, for example, 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2HPLC of Formula: 98-60-2)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties.HPLC of Formula: 98-60-2 Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.
