Title (EN) SPIRO[CHROMAN-2,2'-INDOLE] DERIVATIVES AS CYANIDE ION CHEMOSENSORS
(FR) DÉRIVÉS DE SPIRO[CHROMAN-2,2'-INDOLE] À UTILISER EN TANT QUE CHIMIOCAPTEURS D'ION CYANURE
Abstract: front page image
(EN)The invention describes new spiro[chroman-2,2'-indole] derivatives of formula (I). When compounds of the invention, 1',3',3,4-tetrahydrospiro[chromen-2,2'-indoles], are treated with solution containing cyanide ions, 3,4-dihydropyrane ring opening occurs, resulting in formation of colored 4-nitrophenolate ion, which is detectable colorimetrically.
(FR)L'invention concerne de nouveaux dérivés de spiro[chroman-2,2'-indole] de formule (I). Lorsque les composés de l'invention, 1',3',3,4-tétrahydrospiro[chromène-2,2'-indoles], sont traités avec une solution contenant des ions cyanure, une ouverture de cycle 3,4-dihydropyrane se produit, ce qui entraîne la formation d'ion 4-nitrophénolate coloré, lequel est détectable par colorimétrie.
