Visible-light induced three-component reaction for α-aminobutyronitrile synthesis by C–C bond formation using quantum dots as photocatalysts

Abstract

We describe a three-component reaction of malononitrile, benzaldehyde and N,N-dimethylaniline using aluminium doped CdSeS/CdZnSeS(Al)/ZnS quantum dots (QDs) as visible light catalyst to synthesize α-aminobutyrilitriles under room temperature and mild conditions....

Advancements in semiconductor quantum dots: expanding frontiers in optoelectronics, analytical sensing, biomedicine, and catalysis

“…With the help of this procedure, they synthesized a series of γ-amino nitriles. 304 Brian Malile et al developed Mn 2+ -doped CdS/ZnS core/shell CQDs (denoted as Mn:CdS/ZnS or doped CQDs) as photoredox catalysts for model organic reactions including the photoreduction of methyl viologen, dehalogenation of meso-1,2-dibromo-1,2-diphenylethane, and the photoreduction of nitrobenzene to aniline (Fig. 26C).…”

Photocatalytic formation of P–S bonds via CdSeS/CdZnS quantum dots under visible light irradiation

“…More recently, semiconductor materials such as colloidal quantum dots (QDs) have also been employed as photocatalysts in visible light induced reactions. 35–37 By virtue of their unique structures, these colloidal quantum dots possess excellent photostability and high molar extinction coefficients in a wide spectral absorption range for efficient utilization of sunlight. All these advantageous properties make them promising new types of catalysts in photocatalytic organic transformations.…”
