Lewis‐Acidic Properties and Catalytic Behavior of Hydroboration‐ and Diolysis‐Derived NHC‐Stabilized Borenium Cations

open access: yesChemistry – A European Journal, EarlyView.
A series of thirteen (N‐heterocyclic carbene) NHC‐stabilized borenium cations is synthesized from NHC→BH3 complexes via hydroboration and condensation with diols. The novel compounds are fully characterized. Eight crystal structures are presented. Kinetic and NMR data show how the structural features translate to catalytic activity in hydrosilylation ...

Associations between serum pentadecanoic acid (C15:0) and heptadecanoic acid (C17:0) levels and hypertension: a cross-sectional analysis of NHANES data

open access: yesLipids in Health and Disease
Background Pentadecanoic acid (C15:0) and heptadecanoic acid (C17:0) are considered to have protective effects on cardiovascular health. However, research on the relationship between C15:0 and C17:0 levels and hypertension remains limited.

Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

open access: yesChemistry – A European Journal, EarlyView.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...
