Highly selective, colorimetric probes for cyanide ion based on β-formylBODIPY dyes by an unprecedented nucleophilic addition reaction
Two β-formylBODIPYs with strong daylight excitable fluorescence and highly selective visual and colorimetric responses to cyanide anion (CN–) have been prepared. NMR titration experiments have been performed to study the sensing mechanism for t
FormylBODIPYs: Privileged Building Blocks for Multicomponent Reactions. the Case of the Passerini Reaction
Eleven formyl-containing BODIPY dyes were prepared by means of either the Liebeskind-Srogl cross-coupling reaction or the Vilsmeier reaction. These dyes were used as components in the Passerini reaction to give highly substituted BODIPY dyes. A joined spe
α-/β-formylated boron-dipyrrin (BODIPY) dyes: Regioselective syntheses and photophysical properties
Formylation has been performed on pyrrole-unsubstituted dipyrromethanes 1 and boron-dipyrrin (BODIPY) dyes 4 based on a Vilsmeier-Haack reaction. It is highly regioselective and complementary and occurs exclusively at the α-and β-position, respectively, f
