Trigonal Planar Bis(carbene)Cu(I) Complexes Enable Divergent H2 Activation with H2O for Accelerated Olefin Hydrogenation

Angewandte Chemie, EarlyView.
Trigonal planar naphthyridine‐bis(carbene)Cu(I) alkyl, hydroxide, and ethoxide complexes promote a divergent mechanism of H2 activation for the rare catalytic hydrogenation of unactivated alkenes at mild conditions at copper. Abstract CuH‐catalyzed olefin hydrogenation is rare compared to those of carbonyl‐derived substrates. Olefin insertion into Cu–H

Synthesis and Structure of Neopentyl Sodium: A Hydrocarbon‐Soluble Reagent for Controlled Sodiation of Non‐Activated Substrates

Angewandte Chemie, EarlyView.
Displaying strong controlled metalating power, hydrocarbon‐soluble sodium neopentyl can deprotonate challenging non‐activated arenes and alkenes, with sodiated intermediates successfully undergoing onward functionalisation reactions. By characterising key reaction intermediates, and running computational studies on models, insight has been gained on ...

A Rational Investigation of the Lewis Acid-Promoted Coupling of Carbon Dioxide with Cyclohexene Oxide: Towards CO₂-Sourced Polycyclohexene Carbonate under Solvent- and Cocatalyst-Free Conditions

C, 2019
We report a rational investigation of the selective synthesis of poly(cyclohexene carbonate) from CO2 and cyclohexene oxide by using commercially available Lewis acids with nontoxic metal centers.

Microwave Spectrum of Cyclohexene [PDF]

Bulletin of the Chemical Society of Japan, 1969
Abstract The microwave spectrum of cyclohexene has been investigated in the frequency region from 7.3 to 27 Gc/sec with a conventional Stark modulation spectrometer, and the spectrum in the ground vibrational state has been assigned.

trans-Cyclohex-2-ene-1,4-diyl bis(4-nitrophenyl) dicarbonate

Acta Crystallographica Section E, 2008
Although the title molecule, C20H16N2O10, does not possess molecular inversion symmetry, it lies on a crystallographic inversion centre which imposes disorder on the central cyclohexene ring.

Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

Advanced Theory and Simulations, EarlyView.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...
