The reaction of molecular oxygen with palladium(0) centers is a key step in Pd-catalyzed aerobic oxidation reactions. The present study provides a density functional theory (DFT) computational analysis of the mechanism and electronic structural features of the reversible, associative exchange between O(2) and ethylene at an ethylenediamine (en)-coordinated palladium(0) center. Salient features ...

Dedicated to Professor Hubert Schmidbaur on the occasion of his 75 th birthday The reactions of Zintl ions Sn9 4− formed in ethylenediamine solutions of K2Cs2Sn9 and Rb4Sn9 with elemental tellurium have been investigated. Addition of elemental tellurium to the filtrates of these solutions leads – depending on the reaction conditions – to four different products: Compounds K0.36(1)Cs3.64(1)[SnTe...

Glutaraldehyde causes especially high autofluorescence. It reacted with proteins and peptides to generate visible to near-IR emitters. A model indicated that ethylenediamine and a secondary amine in the molecule were key components for the formation of emissive species. The mechanism enables us to control the generation and elimination of autofluorescence.

Solid-state magnesium ion conductors with exceptionally high ionic conductivity at low temperatures, 5 × 10-8 Scm-1 at 30 °C and 6 × 10-5 Scm-1 at 70 °C, are prepared by mechanochemical reaction of magnesium borohydride and ethylenediamine. The coordination complexes are crystalline, support cycling in a potential window of 1.2 V, and allow magnesium plating/stripping. While the electrochemical...

Physical and chemical stability of suppositories containing aminophylline and various bases prepared in our hospital pharmacy was investigated. Ethylenediamine in aminophylline decreased, the melting points of the suppositories rose, and the disintegration and liquefaction times were prolonged in suppositories with Witepsol base when stored at room temperature. Thin-layer chromatography produce...

We introduce a facile method to prepare an n-type reduced graphene oxide field effect transistor at room temperature via a typical Benkeser reduction using lithium and ethylenediamine.

The synthesis of modified carbon dots (N-CDs) from nanocrystalline cellulose, as the source, with combination urea and ethylenediamine, nitrogen dopant agents, was successfully carried out by pyrolysis at 300°C. N-CDs
