in this investigation, a facile and green sonochemical route has been developed for the synthesis of 2-ketomethylquinolines by using 2-methylquinolines and several acyl chlorides in the presence of nanocrystalline mgal2o4 as an efficient heterogeneous catalyst. the combination of nanocatalyst and ultrasonic process afforded corresponding ketomethyl quinolines in shorter reaction durations, and ...

(Hetero)aryl bis-acid chlorides and terminal alkynes, or likewise acid chlorides and terminal dialkynes, and ethyl 2-mercaptoacetate can be reacted to give highly luminescent symmetrical terthiophenes and quinquethiophenes in the sense of a consecutive pseudo-five-component reaction in good to excellent yields. Further functionalization of the obtained oligomers can be readily achieved by halog...

1his thesis is the flfst report of reactions of atomic calbon with acid chlorides. Carbon is known to react with phosgene to afford dichlorocarbene. We report a similar reaction with carbon and acid ch~lorides, generating alkylchlorocarbenes. We examine both the nature of the carbene products generated through deoxygenation and the general reacliviry ofcarbon with the acid chlorides. We report ...

The catalytic performance of various metal chlorides in the conversion of cellulose to levulinic acid in liquid water at high temperatures was investigated. The effects of reaction parameters on the yield of levulinic acid were also explored. The results showed that alkali and alkaline earth metal chlorides were not effective in conversion of cellulose, while transition metal chlorides, especia...

in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...

Manganese-induced early biochemical changes and effects of supplementation of magnesium nitrate (Mg(NO3)2) and antioxidant vitamins (A, C, D and E) were studied in rats intoxicated with manganese. Significant elevation in the level of chlorides in plasma, erythrocytes, liver and cerebellum, and a decrease in plasma inorganic phosphate (pi) with an increase in liver pi were observed in animals e...
