Geminal Difunctionalization of Ketones via C─S Bond Insertion of Photogenerated Donor–Donor Diazo Compounds

Angewandte Chemie International Edition, EarlyView.
Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

Angewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...

Combined Gravimetric, Electrochemical, and Computational Research on Benzothiophene Derivatives as Effective Corrosion Inhibitors for Mild Steel

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Four benzothiophenes, thianaphthene (BT‐1), 3‐bromothianaphthene (BT‐2), benzo[b]thiophene‐2‐carboxaldehyde (BT‐3), and benzo[b]thiophene‐2‐carbonitrile (BT‐4), were tested as mild steel corrosion inhibitors in 1‐M HCl. The compounds have the similar benzothiophene core but differ in the substituents bound to the ring.

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.
