Comparing intermediate range order for alkyl- vs. ether-substituted cations in ionic liquids.

Chem Commun (Camb)

Published: May 2012

X-ray scattering data from four pairs of ionic liquids (ILs) are compared. The alkyl-substituted cations show a first sharp diffraction peak between 3 and 4 nm(-1) that is not observed for ILs having cations with ether- or hydroxy-substitutions. These observations indicate a significant difference in the intermediate range order for these liquids.

Rice (Oryza sativa) is a vital food crop and staple diet for most of the world's population. Poor dietary choices have had a significant role in the development of type-2 diabetes in the population that relies on rice and rice-starch-based foods. Hence, our study investigated the in vitro digestion and glycemic indices of certain indigenous rice cultivars and the factors influencing these indices.

Introduction And Importance: Retiform hemangioendothelioma(RH) is a rare vascular tumor affecting patients over a wide age range without a gender predilection; only about 50 cases have been described so far.

Case Presentation: We report a case of submandibular retiform hemangioendothelioma in a 58-year-old woman who had been diagnosed with RH 20 years ago and had experienced recurrence four times during the past 20 years. This will increase the limited number of such cases in the hope of gaining a better understanding of this rare type of tumor.

College of Materials Science and Engineering, Fuzhou University, Fuzhou 350108 China. Electronic address:

The development of high-performance electrocatalysts for hydrogen evolution reaction (HER) in different pH conditionsis pivotal in producing green hydrogen, but remains challenging. Herein, we regulate the p-d orbitals hybridization between B and Pt for effective and durable HER at all pH ranges by controlling the inserted B atom. Consequently, the optimized B-doped Pt catalysts with 20 at.

Homo-Mannich Reaction of Cyclopropanols: A Versatile Tool for Natural Product Synthesis.

Acc Chem Res

January 2025

ConspectusThe Mannich reaction, involving the nucleophilic addition of an enol(ate) intermediate to an imine or iminium ion, is one of the most widely used synthetic methods for the synthesis of β-amino carbonyl compounds. Nevertheless, the homo-Mannich reaction, which utilizes a homoenolate intermediate as the nucleophilic partner and provides straightforward access to the valuable γ-amino carbonyl compounds, remains underexplored. This can be largely attributed to the difficulties in generation and manipulation of the homoenolate species, despite various homoenolate equivalents that have been developed.
