This study uses density functional theory (DFT) calculations at the M06‐2X/6–311 + G(d,p) level to explore the potential of main group non‐metals (X = O, N, S, P) to form hypervalent ylides (RmX+–YRn−2−). Substituent effects (R = alkoxy, alkyl, phenyl, H,

Merging the Reactivity of (Pseudo)cyclic Hypervalent Iodine Reagents and Carbenes or Carbenoids
SynthesisIn this short review, we present applications merging the reactivity of cyclic hypervalent iodine reagents with carbenes and carbenoids developed in the period 2014–2024. The use of more stable cyclic hypervalent iodine reagents has led to major advances

Methionine-Specific Bioconjugation for Single-Molecule Force Spectroscopy of Cell Surface Proteins.
ACS NanoCell surface proteins play crucial roles in various cellular processes, including intercellular communication, adhesion, and immune responses. However, investigating these proteins using single-molecule force spectroscopy (SMFS) has been hindered by ...

The π electron systems are the conventional electron donors to the hydrogen acceptors in hydrogen bonding. Apart from the hydrogen atom, halogens, chalcogens, pnicogens and triel/tetrel atoms can also be envisaged as electron acceptors involving π clouds.

The conjunction of aromaticity and hypervalency: the C5H5SF3 molecule 1,1,1-trifluorothiabenzene
Journal of Molecular Structure: THEOCHEM, 1991Abstract Ab initio quantum mechanical methods have been applied to the molecule formed via the intimate union of benzene and sulfur hexafluoride. The self-consistent-field (SCF) method has been used with a full double zeta (DZ) basis extended by a set of d functions on sulfur and also with the DZ basis extended by polarization functions on all ...

Sulfuranes Lacking Benzoannelation. Sulfuranes and Other Hypervalent Molecules Studied by 17O-NMR
The Journal of Organic Chemistry, 1999The rates of hydrolysis of benzoannelated vs nonbenzoannelated sulfuranes, viz. 5 vs 3 or 5 vs 4, were compared. Benzoannelation was found to provide very modest kinetic stabilization. Crystal structures of sulfuranes 3 and 4 were obtained and compared with each other, with a dibenzoannelated sulfurane, 17, and with a non-sulfurane analogue of 4.
