30 Importantly, when quinone 80 was subjected to L-selectride in THF at −78 °C, α-methoxyketone 81 was formed in 86% yield (over two steps), while no formation of the corresponding 1,2-reduction product was observed (Scheme 7.19). We hypothesize that ring strain release of quinone ...
trimethyl benzene, C6H3(CH3)3; (5) with acetyl chloride plus anhydrous aluminum chloride (Friedel-Crafts reaction) to form acetophenone (methylphenyl ketone), C6H5COCH3. General Description Benzene appears as a clear colorless liquid with a petroleum-like odor. Flash point less than 0 °F....
The variety of products formed in the course of benzene oxidation byAaeAPO reflects its ability to hydroxylate, in addition to benzene, also phenol and dihydroxybenzenes, which further undergo oxidation into quinones. It is reasonable that phenol represents a better substrate than the little activat...
MANUFACTURE OF PHENYLKETONE FROM HALOGENO OR TRIHALOGENOMETHYLBENZENE AND TRIHALOGENOMETHYLATED FATTY OR AROMATIC COMPOUNDThe invention relates to a method of preparation of phenylketones characterizes in that, in a first step, halogeno react a trihalomethylbenzene with a compound or aliphatic or ...
The sulfonation of cyclopropylbenzene (1a) and cyclopropyl phenyl ketone (5) with sulfur trioxide in both nitromethane and 1,4-dioxane as solvent has been studied. Sulfonation of cyclopropylbenzene (1a) with up to 2.0 mol-equiv. of SO3 in dioxane leads to the initial formation of 3-phenyl-...
During last decade there has been an increase in the interest of substituted benzenesulfonic acids derivatives especially, benzenesulfonyl hydrazones due to wide spectrum of bioactivity of this class of compounds which include: antibacterial [1–8], antifungal [3–5, 9–12], anticancer [13–21],...
One-pot synthesis of α-phenylsulfinyl ketones by reaction of phenyl benzenethiosulfinate with enolate anions, and synthesis of sulfoxides and sulfides by ... Phenyl benzenethiosulfinate reacts with enolate anions derived from ketones to give α-phenylsulfinyl ketones directly, together with minor ...
The reaction in the absence of a solvent at 140-150 掳C leads to the formation of 3,5-diaryl-1,2,4-oxadiazoles ( ). The reaction carried out in solvents (benzene, toluene, nitrobenzene, pyridine) in the broad temperature ... LI Belen'Kii,DB Brokhovetskii,M Krayushkin - 《Tetrahedr...
