The a,b-CCC agostic bonding in metallacyclobutanes is examined on the basis of structural, bonding, energetics, and electron density features. The structural features such as Ca–Cb, M–Ca, and M–Cb distances and CaCbCa and ...

The effect of site selective doping of Sm on the superconducting and flux pinning properties of (Bi, Pb)-2212 superconductor has been investigated. Pure, Sm substituted at different cationic sites such as Bi, Sr and Ca, ...

Seed oils from the indigenous species, viz., Annona squamosa, Annona muricata and Annona reticulata belonging to Annonaceae family have been analyzed for their physico-chemical properties. Major fatty acids identified from ...

Desymmetrization of fulvene-derived bicyclic hydrazines by a palladium/Lewis acid catalyzed reaction with allyl and vinyl stannanes leading to the efficient synthesis of synthetically important alkylidene cyclopentenes is ...

The enone moiety of 3-bromo-7-(bromomethyl)tetracyclo[5.3.1.02,6.04,8]undec-10(12)-ene-9,11-dione undergoes facile hetero-Diels–Alder reaction with pentafulvenes leading to novel cage systems with pyran moiety.

Various 4-acylbis(1-phenyl-3-methyl-5-pyrazolones), namely, 4-adipoylbis(1-phenyl-3-methyl-5-pyrazolone) (H 2 AdBP), 4-sebacoylbis(1-phenyl-3-methyl-5-pyrazolone) (H2SbBP) and 4-dodecandioylbis(1-phenyl-3-methyl-5-pyrazolone) ...

Nucleophilic heterocyclic carbene-catalyzed cyclopentannulation of enals and chalcones via homoenolate has been observed for the first time. Serendipitously, the reaction lead to a very efficient synthesis of 3,4-trans-d ...

A study on the synthetic utility of [6+3] cycloaddition of pentafulvenes with 3-oxidopyrylium betaines is described. 5-8 Fused oxa-bridged cyclooctanoids, the products of the above methodology undergo facile Diels-Alder ...

A new thermodynamic scale of aromaticity is devised for a large spectrum of organic molecules using isodesmic reactions. The present scale named E-aroma quantifies aromaticity as the average stabilization of a conjugated ...

A two-layer ONIOM(B3LYP/6-31G(d, p): UFF) quantum mechanics (QM) -molecular mechanics ( MM) optimization of PR3 ligands, where the QM layer is always constructed as PH3, followed by molecular electrostatic potential ( MESP) ...
