A general method for one-pot synthesis of thioamides is developed through a three-component reaction involving chlorohydrocarbon, amide and elemental sulfur. Such a strategy does not only avoid residual transition metal in the product but also prevent the generation of C-N coupling byproduct. The latter is prone to be generated when alkane halide and amine are present. With the protocol proposed in this work, both alkyl and aryl thioamides can be obtained in moderate to excellent yields with a high tolerance of various functional groups. External oxidants are not required in the reaction. In addition, the reaction mechanisms are addressed using a combination of controlling experiments and quantum chem. calculations

Cao, Chaotun published the artcileQuantifying and fine adjusting the solid-state fluorescence wavelength of 1-thienyl-2-arylethylene, Recommanded Product: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Journal of Luminescence (2021), 117895, database is CAplus.

Thirty two 1-thienyl-2-arylethylene derivatives (XAEY) were synthesized and their solid-state fluorescence emission wavelengths Em (nm) were determined The effects of substituents X and Y on the fluorescence wavelengths were analyzed in detail. The quant. correlation anal. for the Em was carried out by employing the ground-state polarity parameters and excited-state parameters of the substituents X and Y. A quant. equation was obtained and its reliability was verified by the leave-one-out (LOO) method. The obtained results show: (1) For the compounds XAEY, when the group Y on the aryl group is fixed, the Em order is 2′-methyl-2-thienyl-AEY > 3-thienyl-AEY > 2-thienyl-AEY; when thienyl (X) is fixed, the Em of XAEY with electron-withdrawing group Y is longer than that of XAEY with electron-donating group Y; (2) The Em of XAEY can be finely adjusted by changing groups X and Y. That is, one can obtain a series of compounds with continuous fluorescence emission wavelength in range of 450-600 nm via selecting different groups X or Y. (3) The 2′-Me has an addnl. red shift effect on the Em of 2′- methyl-2-thienyl-AEY. The results of this paper can provide an important reference for studying theor. solid-state fluorescence emission spectra of organic compounds and designing corresponding fluorescent material mols.

A selenium-mediated redox condensation of 2-chloronitrobenzenes 2-Cl-RC₆H₃NO₂ (R = H, 4-Me, 5-F, 5-CF₃, etc.) and arylmethyl chlorides R¹CH₂Cl (R¹ = Ph, naphthalen-1-yl, pyridin-3-yl, etc.) to obtain 2-arylbenzoselenazoles I (R² = H, 6-Me, 5-F, 5-Br, etc.) has been realized under metal-free condition. The reactions proceeded in moderate-to-good yields with good functional compatibility and gram-scale achievement. Primarily mechanistic investigation suggested that key intermediate Bn(Se)nBn II, was first isolated and confirmed by NMR.
