1. Replacement of the hydroxyl group with a chlorine atom using phosphorus(V) chloride. 2. Reaction with acyl halides to form esters of carboxylic acids. 3. Reaction with haloalkanes under alkaline conditions to give mixed alkyl–aryl ethers. In addition phenol can undergo further substitution ...
[38] synthesized trithiocyanurate functionalized bamboo hydrochar after acylation with chloroacylchloride followed by treatment with trithiocyanuric acid in alkali condition [38]. Madduri et al., [39], treated pinewood hydrochar with oxone to get carboxylate rich hydrochar after oxidation of phenol ...
2,5-bihydrazino-1,3,4-thiadiazole was synthesized by the reaction of 2,5-bimer capto-1,3,4-thiadiazloe with hydrazine hydrate and reacted with p-ethoxy benzopyl chloride to produce 2,5-biacylhydrazino-1,3,4-thiadiazole,which was further cycled by POCl3 as cyclization agent to produce ...
5-acetylamino-1,3,4-thiadiazole-2-sulfonyl chloride compound has been synthesized using 5-amino-2-mercapto-1,3,4-thiadiazole, and the compound were been acyltion and oxidation by gaseous chlorine. 以5-氨基-2-巯基-1,3,4-噻二唑为原料,经过胺基酰基化、氯气氧化制得5-乙酰胺基-1,3,4-噻二...
In this case no external nucleophile was supplied and the final acyl palladium complex lactonized via enolization of a carbonyl group.84 (34) Show moreView chapterExplore book A critical review of the 2000 literature preceded by two chapters on current heterocyclic topics John D. Hepworth, B. ...
Exposure of the diazonium salt1107to iodide ion generates an aryl radical, which undergoes intramolecular homolytic substitution at sulfur to liberate the acyl radical intermediate1108. Anexo-mode cyclization with concomitant incorporation of iodide then occurs to afford the 3-disubstituted-chroman-4-one...
If you halogenate the p-position you can use Pd-chemistry to get the acyl-derivative. Thanks, these are good suggestion for mono-acylation, however making siliconfluorescein requires a double reaction with both aromatic rings, so I'm not sure that the second step would proceed with these meth...
