Synthetic platform for mono-functionalised tridentate macrocycles as key precursors of mechanically-linked macromolecular systems

Autor: Evelyne Van Ruymbeke, Jagadeesh Malineni, Sina Ghiassinejad, Simon Box, Charles-André Fustin, Atul Kumar Sharma

Publikováno v: Organic Chemistry Frontiers, Vol. 8, p. 2383-2392 (2021)

We report here a synthetic platform toward mono-functionalized tridentate macrocycles based on a pyridine-2,6-bis-carboxamide motif. These macrocycles bear a variety of functional groups at the fourth position of the pyridine, giving access to a wide

An Indefinitely Air-Stable σ-NiII Precatalyst for Quantitative Cross-Coupling of Unreactive Aryl Halides and Mesylates with Aryl Neopentylglycolboronates

Autor: Jagadeesh Malineni, Na Zhang, Ryan L. Jezorek, Virgil Percec

Publikováno v: Synthesis. 48:2795-2807

Three classes of Ni precatalysts based on π-NiII, π-Ni0 and σ-NiII complexes have been elaborated and employed in different laboratories for the functionalization and cross-coupling of otherwise inert aryl C–O, C–Cl, and C–F electrophiles. V

An efficient N-heterocyclic carbene based ruthenium-catalyst: Application towards the synthesis of esters and amides

Autor: Jagadeesh Malineni, Helmut Keul, Carina Merkens, Martin Möller

Publikováno v: Catalysis Communications. 40:80-83

A highly stable benzimidazolylidene based N-heterocyclic carbene (NHC) ruthenium catalyst was prepared starting with readily accessible starting materials. Under inert gas atmosphere and in air the catalyst showed high activity for the direct synthes
