Gram‐Scale Photocatalysis with a Stable and Recyclable Chromium(III) Photocatalyst in Acetonitrile and in Water

Advanced Synthesis &Catalysis, Volume 367, Issue 10, May 20, 2025.
Abstract The use of stable photosensitizers made on a multigram‐scale from cheap and available starting materials offers an extraordinary opportunity to translate small‐scale proof‐of‐concept photoreactions to widespread applications in non‐specialized laboratories, thereby promoting the implementation of light‐driven syntheses.

Synthesis and catalytic activity of metallo-organic complexes bearing 5-amino 2-ethylpyridine -2-carboximidate

Journal of Chemical Sciences, 2016
A series of copper, cobalt, nickel and manganese complexes were synthesized and characterized. Reaction of 5-amino-2-cyanopyridine with MCl2⋅xH2O (M: Cu2+, Co2+, Ni2+, Mn2+) in anhydrous ethanol resulted in the formation of four complexes [NH2EtPyCuCl2(CH3OH)].H2O 1, [(NH2EtPyHCl)3Co] (Cl)3.3H2O 2, [(NH2EtPy)22(H2O)Ni](Cl2) 3, and [(NH2EtPy)22(H2O)Mn ...

Cerium‐Catalyzed Ritter‐Type C−H Amination of Alkylarenes

European Journal of Organic Chemistry, Volume 28, Issue 5, February 3, 2025.
A new photocatalytic strategy for Ritter‐type amination of alkylarenes with nitriles is reported, in which the alkylarene is first brominated by CBr3COOH under Ce(III) catalysis and blue light irradiation, and the resulting bromide then undergoes the normal Ritter reaction to afford the amide product. Abstract Reported here is a photocatalytic strategy

Biochemical Profiling and Bioactivity of Five Selected Microalgae Species as Potential Sources of Bioactive Compounds for Nutritional and Biotechnological Applications

Journal of Food Biochemistry, Volume 2025, Issue 1, 2025.
Microalgae have emerged as promising sustainable sources of bioactive compounds, essential for addressing global challenges. This study investigated the biochemical profiles of five microalgae species: Nannochloropsis sp., Tetraselmis chuii, Chaetoceros muelleri, Thalassiosira weissflogii, and Tisochrysis lutea. By using NMR spectroscopy, organic acids,

Design and Synthesis of Multipath Compact Cyclophanes for Quantum Interference Studies

European Journal of Organic Chemistry, Volume 27, Issue 48, December 23, 2024.
Macrocyclic model compounds with two parallel conductance paths are reported. Preliminary single molecule transport studies reflect the impact of substitution patterns of the different pathways. From a synthetic viewpoint interesting, the fragility of the thiophene model compounds required the consideration of alternative protection group strategies ...
