Switchable Reactivity of Cyclopropane Diesters toward (3 + 3) and (3 + 2) Cycloadditions with Benzoquinone Esters

Autor: Navpreet Kaur, Pankaj Kumar, Arijit Hazra, Prabal Banerjee

Publikováno v: Organic letters. 24(44)

Herein, we describe an unprecedented (3 + 3) cycloaddition reaction of the donor-acceptor cyclopropanes with quinone esters toward the construction of chroman scaffolds in moderate to good yields. Interestingly, the strategy is also adjustable toward

Numerical simulation of Bloch equations for dynamic magnetic resonance imaging

Autor: Arijit Hazra, Gert Lube, Hans-Georg Raumer

Publikováno v: Applied Numerical Mathematics. 123:241-255

Magnetic Resonance Imaging (MRI) is a widely applied non-invasive imaging modality based on non-ionizing radiation which gives excellent images and soft tissue contrast of living tissues. We consider the modified Bloch problem as a model of MRI for f

Optimal, globally constraint-preserving, DG(TD)2 schemes for computational electrodynamics based on two-derivative Runge-Kutta timestepping and multidimensional generalized Riemann problem solvers – A von Neumann stability analysis

Autor: Arijit Hazra, Dinshaw S. Balsara, Roger Käppeli, Praveen Chandrashekar

Publikováno v: Journal of Computational Physics. 408:109238

Discontinuous Galerkin (DG) methods have become mainstays in the accurate solution of hyperbolic systems, which suggests that they should also be important for computational electrodynamics (CED). Typically DG schemes are coupled with Runge-Kutta tim

Globally constraint-preserving FR/DG scheme for Maxwell's equations at all orders

Autor: Dinshaw S. Balsara, Praveen Chandrashekar, Arijit Hazra

Computational electrodynamics (CED), the numerical solution of Maxwell's equations, plays an incredibly important role in several problems in science and engineering. High accuracy solutions are desired, and the discontinuous Galerkin (DG) method is

Alkali metal ion mediated self-assembly of vanadium(V) ions and pyrazole based polydentate ligands leading to the formation of helix, double helix and supramolecular cage-like structures

Autor: Atanu Jana, Kinsuk Das, Somnath C. Roy, Arijit Hazra, Samik Gupta, Tarak Nath Mandal, Ray J. Butcher, Saugata Konar, Sangita Ray, Susanta Kumar Kar

Publikováno v: Polyhedron. 30:187-194

The anionic cis-dioxovanadium(V) complex species LVO2− and L1VO2− of two tridentate ONO ligands (H2L and H2L1) can bind alkali metal ions in a bis-monodentate fashion like a bridging carboxylate group. Here H2L (N′-[(E)-(2-hydroxyphenyl)methyli

Molybdenum(VI) complexes of a few pyrimidine derived ligands and the study of metal mediated CN bond cleavage resulting in ligand transformation during complex formation

The syntheses of dioxomolybdenum(VI) complexes were attempted using the Schiff base ligands HL1 and HL2. The ligands were prepared by the condensation of 4,6-dimethyl 2-hydrazino pyrimidine with salicyl aldehyde (for HL1) and o-hydroxy acetophenone (
