Naphthoxide ion
WitrynaThe photosensitized dechlorination of isomeric mono- and dichloronitrobenzenes has been studied in the presence of naphthoxide ion in alkaline medium. The 100W tungsten lamp was used for irradiation.

Witryna1 kwi 2008 · The mechanism of the carboxylation reaction of sodium 2-naphthoxide (NaphONa) was investigated in the positions 1, 3, and 6 by means of three methods: B3LYP, B3LYP-D2, and M06-2X. Witryna1 sty 1988 · With the 2-iodonaphtalenes6 3, _4 and _5, the variously substituted 1,2'-binaphthyl derivatives 7, 8 and 9 were obtained. - The 1-naphthoxide ion _10, treated with _2, gave the 1,1'-binaphthyl _11, the 1,2'-binaphthyl _12 and the disubstitution product _13, resulting from reaction on positions 2 and 4 of _10 where the negative …
WitrynaSodium phenoxide ( sodium phenolate) is an organic compound with the formula NaOC 6 H 5. It is a white crystalline solid. Its anion, phenoxide, also known as phenolate, is … Witryna24 sty 2003 · The increase in OH − ion concentration increases the sensitivity of the sensitizer, which shows higher proton transfer of 2-naphthol. C 10 H 7 OH + OH − ⇌ C 10 H 7 O − + H 2 O This equilibrium between naphthol and naphthoxide ion is sensitive to OH − ion concentration of the solution. It is reported that fluorescence of …
WitrynaThe sodium naphthoxide is a much better nucleophile because it dissociates into ions forming a naphthoxide ion. The naphthol is not negatively charged and is not as electron rich. Why is it important to fully cool the product in an ice bath prior to isolation by suction filtration? Why do you need to rinse your product with ice water instead of ... WitrynaThe fluorescent excited state of the 2-naphthoxide ion is quenched by aromatic halides as electron acceptors according to an electron-transfer mechanism (Arguello, J.E.; Peñeñory, A.B. J. Org. Chem. 2003, 68, 2362-2368). In the propagation step, 2-naphthoxide ions react with the aromatic radical and the substitution product is …
