Treatment of [UO(2)(Ar(2)nacnac)Cl](2) with 4 equiv. of Li(C(4)H(5)N(2)) results in the formation of a rare uranyl organometallic complex [Li(MeIm)][UO(μ-O)(Ar(2)nacnac)(μ-C,N-C(4)H(5)N(2))(2)] (2), in moderate yield. Reaction of 2 with 1 equiv. of MCl(2) (M = Fe, Co) yields the bimetallic complexes [MCl(MeIm)][UO(2)(Ar(2)nacnac)(μ-N,C-C(4)H(5)N(2))(2)] (M = Fe, 3; M = Co, 4).

Continuous misuse of difenoconazole (DFZ) results in farmland contamination, posing risks to crops and human health. Salicylic acid (SA) has been shown to enhance plant resistance and reduce pesticide phytotoxicity and accumulation. However, whether SA effectively reduces DFZ phytotoxicity and accumulation and its underlying mechanisms remain poorly understood.

The manuscript describes the development of an efficient synthetic route to cinnolines, facilitating faster access to JNJ-8003 related Respiratory Syncytial Virus (RSV) non-nucleoside (NNI) inhibitors. Starting from correctly functionalized aryl halides, a Sonogashira reaction followed by SNAr reaction with hydrazine 1,2-dicabroxylate reagents provided dihydrocinnolines directly via in situ 6-endo-dig cyclization. The dihydrocinnolines were conveniently transformed to corresponding cinnolines in one step.

Nanoclusters are nanometer-sized molecular compounds characterized by significant metal-metal bonding and low average oxidation states, and they exhibit unique properties distinct from those of small metal complexes or nanoparticles. Unlike noble metals stable in metallic forms, the synthesis of nanometer-sized iron clusters has been precluded by the relatively weak iron-iron bonds and the high reactivity of low oxidation state iron, despite the extensive history of molecular iron compounds. Here, we report the synthesis and characterization of a cationic 55-atom iron cluster with a 1.

Due to their ease of synthesis and large specific surface area, Ni(OH) nanosheets have emerged as promising electrochemical sensing materials, attracting significant attention in recent years. Herein, a series of oxy-hydroxides based on Ni(OH) nanosheets, including NiO/Ni(OH)@NF and (MNi)O/Ni(OH)@NF (M = Co, Fe, or Cr), are successfully synthesized the electrochemical oxidation and incorporation strategies. Electrochemical tests demonstrate that these Ni(OH)-based oxy-hydroxides exhibit excellent electrochemical oxidation activity for glucose in alkaline electrolyte.

This work introduces a mild reaction-condition approach for the direct C-C bond cleavage of amides, resulting in the formation of benzouracil and carbamate structures. This method leverages a C-C bond cleavage strategy that enables nucleophilic addition to the amide carbonyl, involving a reactive spiro intermediate. A diverse range of chloroacetamides were synthesized and utilized as bifunctional starting materials in this transformation.
