The synthetic utility of this protocol was carried out with syn-isomer to yield corresponding cis-aziridines. This protocol was operationally simple for a wide variety of substituted carboxaldehydes and substituted phenacyl bromides.

The interactions between four native and modified beta-cyclodextrins and a benzimidazolium bromide salt were analyzed through UV-Vis and NMR Spectroscopy. The new benzimidazolium salt was obtained by simple and efficient conversion of N-1 substituted 5,6-dimethylbenzimidazole with phenacyl bromide in acetone. In all cases, the complexes stoichiometry was 1:1, as determined from UV-Vis titrations. Based on the values for association constants, the strength of the interactions with benzimidazolium bromide was weakest with the methyl substituted beta-cyclodextrin and strongest with the sulfobutyl

Abstract:

A promising imidazole compound was synthesized through the following route. The reaction of 5-methyl-2-phenyl-1H-imidazole-4-carbohydrazide (1) with carbon disulfide and potassium hydroxide in ethanol (80%) afforded potassium salt (2). Refluxing of (2) with phenacyl bromide (3) in ethanol/water (1:1) gave 2-((5-(5-methyl-2-phenyl-1H-imidazol-4-yl)-1,3,4-oxadiazol-2-yl)thio)-1-phenylethan-1-one (4) in a 76% yield. The structure of the title heterocycle (4) was confirmed by single-crystal X-ray diffraction and nuclear magnetic resonance.

Abstract:

The reaction between phenacyl bromide and 2-mercaptobenzothiazole was studied conductometrically in 17 different protic and aprotic solvents. The second order rate constants determined are found to be highly susceptible to changes in the solvation abilities of the solvents. Correlation of the rate constants with different solvent parameters indicated that the solvation of the reactants and the transition state is due to the electrophilicity, hydrogen bond donor ability, specific polarisability and a non-specific polarity of the solvent. by statistical analysis, a linear solvation energy relati

Abstract:

One of the best ways to design new biocidal agents is synthesizing hybrid molecules by combining two or more bioactive moieties in a single molecular scaffold. So, new series of pyrroles bearing a thiazole moiety were synthesized using 1-methyl-1H-pyrrole-2-carbaldehyde thiosemicarbazones 1a–c. Cyclization of thiosemicarbazone derivatives 1a–c with ethyl chloroacetate, ethyl 2-chloropropanoate, chloroacetone and phenacyl bromide afforded the corresponding thiazolidin-4-ones 2a–c, 5-methylthiazolidin-4-ones 3a–c, 4-methyl-2,3-dihydrothiazoles 4a–c, and 4-phenyl-2,3-dihydrothiazoles 5a–c, respec

Abstract:

We have conducted research into the synthesis and analysis of nellylated-indazole compounds. These compounds were produced through a process involving substituted hydroxycyclohexa-nones, hydrazine hydrate, and phenacyl bromide. Our investigation revealed that, depending on the specific structure of the compounds involved, the reaction can proceed via both nitrogen and oxygen alkylation pathways. The examination of the reactions between 2,6-dicarboxylates and amine derivative hydrochlorides revealed a novel finding: the employment of potassium carbonate as a base facilitates the desired directi

Abstract:

Covalent organic frameworks (COFs) have garnered significant interest within the scientific community due to their distinctive ability to act as organic semiconductors responsive to visible light. This unique attribute makes them up-and-coming candidates for facilitating photocatalytic organic reactions. Herein, two donor–acceptor COFs, TPE-BSD-COF and TPE-BD-COF, have been designed and synthesized by incorporating electron-rich tetraphenylethylene and electron-deficient benzoselenadiazole and benzothiadiazole units into the framework through a Schiff-base polycondensation reaction.
