Synthesis of Schiff and Mannich Bases of Isatin Derivatives with 4-Amino-4,5-Dihydro-1H-1,2,4-Triazole-5-Ones

Molecules, 2008
Ethyl imidate hydrochlorides 1 were prepared by passing HCl gas through solutions of substituted benzyl cyanides and absolute ethanol. Ethoxycarbonylhydrazones 2 were synthesized from the reaction of compounds 1 with ethyl carbazate.

Magnetic Properties of a Two-Dimensional Mixed-Spin System

, 2002
Using a Langmuir-Blodgett (LB) synthesis method, novel two-dimensional (2D) mixed-spin magnetic systems, in which each magnetic layer is both structurally and magnetically isolated, have been generated.

Laser‐Induced Plasma Effects on Bond Breaking in High‐Density Polyethylene Pyrolysis

Advanced Materials Interfaces, EarlyView.
This study introduces a novel application of Laser‐Induced Breakdown Spectroscopy (LIBS) for bond breaking in high‐density polyethylene (HDPE), an area previously unexplored in laser‐plastic interactions. For the first time, a numerical model has been developed to differentiate between photon‐induced and laser field‐induced plasma, demonstrating the ...

Low‐Strain Flexible Ink‐Based Sensors Enable Hyperelastic Inflation Perception Via Geometric Patterning for Balloon‐Type Robots

Advanced Robotics Research, EarlyView.
Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

Illuminating the Path of Rearrangement: Visible Light‐Driven Pd‐Catalyzed Substituted Olefins Synthesis

Advanced Synthesis &Catalysis, EarlyView.
Abstract Pd‐catalyzed reactions are among the most straightforward and efficient methods to proficiently build Csp2‐Csp2 bonds. Nevertheless, thermal activation remains mandatory in most cases, which may decrease the compatibility with sensitive functional groups.

Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

Advanced Synthesis &Catalysis, EarlyView.
An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.

Regio‐, Stereoselective, Aerobic and Metal‐Free Synthesis of Z‐Vinyl Sulfides: One‐Pot Hydroiodination of Internal Alkynes and in situ Sulfenylations

Advanced Synthesis &Catalysis, EarlyView.
Abstract A novel, metal‐free, air‐ and moisture‐compatible one‐pot tandem protocol for the regio‐ and stereoselective synthesis of Z‐vinyl sulfides (achieving yields up to 99%), is reported. This straightforward and efficient process combines the selective hydroiodination of internal alkynes, promoted by the eutectic mixture choline iodide (ChI)/p‐TsOH

eAmidation: An Electrochemical Amidation of Aldehydes via the Oxidation of N‐Aryl Hydrazones

Advanced Synthesis &Catalysis, EarlyView.
The indirect electrochemical oxidation of N‐aryl hydrazones offers an efficient approach to access amides from aldehydes and amines. The AZADO‐mediated reaction enables the selective synthesis of a broad range of valuable amides using readily available aldehydes.
