Structural Dependence of Catenand Effect: Thermodynamic and Kinetic Modulation of Catenane Coordination Properties via Ring‐size and Exocyclic Substituent Variation

open access: yesAngewandte Chemie, EarlyView.
By modifying ring size and exocyclic substituents, effects of ligand interlocking on metal coordination features is explored. Through systematic analysis of CuI catenanes, relationship between structural parameters of the interlocked ligands and coordination properties like geometry, stability, and reactivity is established.

Electrochemical ⍺‐C─H Functionalization of Nitramines for Accessing Bifunctional Energetic Heterocycles

open access: yesAngewandte Chemie, EarlyView.
An electrochemical α‐C─H functionalization of nitramines enables the synthesis of molecules containing bifunctional energetic heterocycles with promising properties. A telescoped, HNO3‐free sequence involving nitration and azolation steps offers a safer, modular, and scalable platform for the synthesis of energetic compounds.

Corrosion inhibition of mild steel in acidic medium by butyl alcohol [PDF]

open access: yes, 2013
The corrosive behavior of mild steel in 1 M H2SO4 solutions contaminated with 3.5 % recrystallized sodium chloride at specific concentrations of butyl alcohol was investigated using potentiodynamic polarization and weight loss technique.

Stereoselective Synthesis of Alkenyl Fluorides and Alkynes by Defluoro Coupling of Trifluoromethyl Arenes

open access: yesAngewandte Chemie, EarlyView.
A practical, stereoselective method for synthesizing tri‐ and tetra‐substituted 1,2‐fluoro‐borylalkenes and alkynes via defluorinative C–C coupling of CF3–arenes with organodiboron reagents is reported. Enabled by a Lewis base activator, products are formed in up to 94% yield and >98:2 Z/E selectivity.
