Abstract: A series of 5-N-arylaminothiazoles were used to form isolable nickel complexes, whose structure was disclosed by X-ray structure analysis, and were used for the detection of zinc halides in solutions with the enhancement of emission properties.

Abstract5‐N,N‐diarylaminothiazoles containing cyano and nitro groups were synthesized using the Pd‐catalyzed Buchwald‐Hartwig amination reaction with good yields. The cyano group in the resultant thiazole was reduced to a formyl group. This was then subjected to the Knoevenagel condensation reaction, leading to the formation of thiazoles with a dicyanovinyl group. The nitro group in the thiazole was reduced to an amino group, which was subsequently reacted with triphosgene, yielding a thiazole with an isocyanate group. These thiazoles, with their electron‐accepting properties, demonstrated absorption and emission spectra at longer wavelengths. Notably, the thiazole containing the dicyanovinyl group displayed a red emission. Tests for the detection of hydrazine, a hazardous volatile organic compound, were conducted using the synthesized thiazoles. The results showed that the dicyanovinyl group effectively responded to hydrazine hydrate, evidenced by changes in the absorption and emission spectra. This change in color was also visibly detectable to the naked eye.

Two-Step Transesterification of Phosphates, Phosphorothioates, and Phosphonates with a Binaphthyl Group for the Synthesis of P-Chirogenic Phosphates and Phosphonates

et al. 2022

Two-step transesterification of four-coordinate pentavalent organophosphorus compounds with a binaphthyl group has been studied in detail. The first step involves transfer of the axial chirality of a binaphthyl group to the central chirality of the phosphorus atom. The second step is the substitution reaction of P-chirogenic compounds with a binaphthyl group with lithium alkoxides to lead to the formation of P-chirogenic phosphates and phosphonates with primary and secondary alkoxy groups.
