Full Heusler

The electronic, magnetic, structural, vibrational, and X-ray absorption spectroscopy of inverse full-Heusler Fe2IrSi alloy has been studied from density functional theory (DFT). The XA-phase with FM-configuration is the most stable one, structurally and thermodynamically.

Copper-catalyzed aerobic oxidative C–H/N–H coupling between simple ketones and diamines was developed toward the synthesis of a variety of pyrazines. Various substituted ketones were compatible for this transformation. Preliminary mechanistic investigations indicated that radical species were involved. X-ray absorption fine structure experiments elucidated that the Cu(II) species 5 coordinated by two N atoms at a distance of 2.04 Å and two O atoms at a shorter distance of 1.98 Å was a reactive one for this aerobic oxidative coupling reaction. Density functional theory calculations suggested that the intramolecular coupling of cationic radicals was favorable in this transformation.
