Proton‐Driven Multistage System Enables Selective Recovery of Gold and Palladium from Electronic Waste Leachate

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Separation and recovery of AuCl4− and PdCl42−, despite their similar physicochemical properties, was accomplished via the selective reductive deposition of Au(III) on PAO hydrogel under strong acid mediation. Selective extraction of precious metals from urban mines plays a crucial role in mitigating the risk of depletion of precious metal resources and

Synthetic Access to the Class of 3‐Amino‐4‐Cyano‐Substituted Thiophenes

European Journal of Organic Chemistry, EarlyView.
The synthesis of 1,1‐dibromo‐3,4,4‐trichloro‐2‐cyano‐1,3‐butadiene opens a first pathway to 3‐amino‐4‐cyano‐thiophenes. These compounds display a push–pull substitution pattern that allows for selective modifications at the 2 and 5 positions. Through S‐oxidation, substitution, and reduction valuable halo and hydrothiophenes are generated, which could ...

Pyrrolo[2,1‐f][1,2,4]triazin‐4‐amine: Synthesis, C7‐Functionalization, and NH2‐Derivatization via Buchwald–Hartwig‐Type Coupling

European Journal of Organic Chemistry, EarlyView.
An optimized synthetic route and regioselective C7/NH2‐functionalization protocols for pyrrolo[2,1‐f][1,2,4]triazine‐4‐amine are disclosed, significantly enhancing accessibility and structural diversification of this relevant N‐heterocycle. An optimized gram‐scale synthetic route to pyrrolo[2,1‐f][1,2,4]triazin‐4‐amine is reported, affording an overall

Synthesis of Novel BINOL Analogs: 3,3′‐Dicarbonyl‐1,1′‐binaphthyl‐4,4′‐diols as Precursors to the Uncharted 5,5′‐Binaphtho[2,1‐d]isoxazole

European Journal of Organic Chemistry, EarlyView.
The parent 5,5′‐binaphtho[2,1‐d]isoxazole and its 3,3′‐dimethyl and 3,3′‐diphenyl derivatives are synthesized via condensation of the respective dicarbonyl compounds with hydroxylamine, followed by cyclodehydration of the resulting dioximes. The dicarbonyl precursors are obtained through 4‐ or 6‐step sequences from 1‐naphthol or 1‐naphthaldehyde ...
