Predicting the Right Mechanism for Hypervalent Iodine Reagents by Applying Two Types of Hypervalent Twist Models: Apical Twist and Equatorial Twist [PDF]
, 2020 Since the hypervalent twist followed by reductive elimination is a general reaction pattern for hypervalent iodine reagents, mechanistic studies about the hypervalent twist step provide significant guidance for experiments. Our previous work showed there are two types of hypervalent twist models, i.e. apical twist and equatorial twist.

A generative model for molecule generation based on chemical reaction trees [PDF]
, 2021 Deep generative models have been shown powerful in generating novel molecules with desired chemical properties via their representations such as strings, trees or graphs. However, these models are limited in recommending synthetic routes for the generated molecules in practice. We propose a generative model to generate molecules via multi-step chemical

Geometrogenesis under Quantum Graphity: problems with the ripening Universe [PDF]
Phys. Rev. D 92, 084007 (2015), 2015 Quantum Graphity (QG) is a model of emergent geometry in which space is represented by a dynamical graph. The graph evolves under the action of a Hamiltonian from a high-energy pre-geometric state to a low-energy state in which geometry emerges as a coarse-grained effective property of space.

Angewandte Chemie, EarlyView.A novel photocatalytic strategy is presented for intermolecular amidative dual functionalization of alkenes using N‐benzoyloxyamides as bifunctional N─O reagents. The method enables efficient olefin 1,2‐amidooxygenation and significantly extends its reactivity to encompass amidoazidation, diamination, and formal anti‐Markovnikov hydroamidation.

Various arsenic network structures in 112-type Ca1-xLaxFe1-yPdyAs2 revealed by synchrotron x-ray diffraction experiments [PDF]
Inorganic Chemistry, 56, (2017) 3033-3035, 2017 Two novel 112-type palladium doped iron arsenides were synthesized and identified using comprehensive studies involving synchrotron x-ray diffraction and x-ray absorption near edge structure (XANES) experiments. Whereas in-plane arsenic zigzag chains were found in 112-type superconducting iron arsenide, Ca1-xLaxFeAs2 with maximum Tc = 34 K, deformed ...
