A new six-armed compounds consist of benzene ring as a central core substituted with aromatic ring and three rod-like armed of 2-chloro-4,6-bis(dodecyloxy)-1,3,5-triazine as the peripheral arms unit which obtained by sequential nucleophilic substitution o... see more

The C18 macro-aromatic carbo-benzene core is a strong chromophoric unit resembling the porphine ring which is prone to quench the emission of fluorophoric substituents. Within the aim of preparing fluorescent carbo-benzenes (and carbo-cyclohexad... see more

Nitrobenzene is one of benzene derivatives. Nitrobenzene can be found naturally and also from the synthesis process. Nitrobenzene is used as a raw material to synthesize aniline, textile dyes, pesticides, and drugs. Nitrobenzene is a solvent in the paint ... see more

We report the organic syntheses of new derivatives  from Chromen-2-one and their  antibacterial activity. Compounds  4-[Acetyl-(2-oxo-2H-chromen-4-yl)-amino]-benzenesulfonyl chloride 1a, 4-[Acetyl-(2-oxo-3-phenylsulfamoyl-2H-chromen-4-yl)-a... see more

A highly efficient protocol was developed for the synthesis of 3-(indoline-1-carbonyl)-N-(substituted)benzenesulfonamide compounds with excellent yields. The in vitro anticancer activity of the new 3-(indoline-1-carbonyl)-N-(substituted)benzenesulfonamide... see more

Background: Exposure to benzene would be associated with many diseases including leukemia. Epigenetic alterations seem to be among the main mechanisms involved.Objective: To determine if chronic occupational exposure to low level of benzene would be assoc... see more

Cetophenone is used as an intermediate in the synthesis of flavones. In industry, Cetophenone is obtained as a by-product of the oxidation of ethyl benzene. The method used for modeling Cetophenone derivatives is a semi-empirical method using (PM6). The c... see more

A green one-pot synthesis of 5H-Chromeno[4,3-b]pyridin-5-one derivatives which are the main core of the natural product of Polyneomarline C is described by the reaction of 4-chloro-3-formyl coumarin and different cyclic and acyclic compounds having active... see more
