Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.Access to pyrazoles arylated at C4 and C5 positions remains challenging due to their similar reactivity under Pd‐catalyzed C–H activation conditions. Herein, we report on the synthesis of 4‐aryl‐5‐heteroarylpyrazoles involving Suzuki‐coupling, followed by Pd‐catalyzed C–H heteroarylation.

Archiv der Pharmazie, Volume 359, Issue 4, April 2026.Biomimetic supramolecular hosts in water affect outcomes and behavior of E/Z‐isomerizations. A deeper understanding of such effects can pave the way to understanding photochemical processes in more complex biological environments. The review displays examples of supramolecular hosts affecting the outcomes of E/Z‐isomerizations and subsequently ...

Asymmetric evolution of magnetic reconnection in collisionless accretion disk
, 2014 An evolution of a magnetic reconnection in a collisionless accretion disk is investigated using a 2.5 dimensional hybrid code simulation. In astrophysical disks, magnetorotational instability (MRI) is considered to play an important role by generating ...

Mechanistic Study of Gold(I)-Catalyzed Intermolecular Hydroamination of Allenes [PDF]
, 2010 The intermolecular hydroamination of allenes occurs readily with hydrazide nucleophiles, in the presence of 3-12% Ph_3PAuNTf_2. Mechanistic studies have been conducted to establish the resting state of the gold catalyst, the kinetic order of the reaction,

Anisotropic Diffusion in Mesh-Free Numerical Magnetohydrodynamics
, 2016 We extend recently-developed mesh-free Lagrangian methods for numerical magnetohydrodynamics (MHD) to arbitrary anisotropic diffusion equations, including: passive scalar diffusion, Spitzer-Braginskii conduction and viscosity, cosmic ray diffusion ...

Vlasov simulations of Kinetic Alfv\'en Waves at proton kinetic scales
, 2014 Kinetic Alfv\'en waves represent an important subject in space plasma physics, since they are thought to play a crucial role in the development of the turbulent energy cascade in the solar wind plasma at short wavelengths (of the order of the proton ...

Inertial range turbulence in kinetic plasmas
, 2007 The transfer of turbulent energy through an inertial range from the driving scale to dissipative scales in a kinetic plasma followed by the conversion of this energy into heat is a fundamental plasma physics process.
