Electron-Deficient Acetylenes as Three-Modal Adjuvants in SNH Reaction of Pyridinoids with Phosphorus Nucleophiles

open access: yesMolecules, 2021
Publications covering a new easy metal-free functionalization of pyridinoids (pyridines, quinolines, isoquinolines, acridine) under the action of the system of electron-deficient acetylenes (acetylenecarboxylic acid esters, acylacetylenes)/P-nucleophiles

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

An Investigation of Some Quinoline and Acridine Derivatives of Possible Therapeutic Value [PDF]

open access: yes, 1937
In this thesis, some new acridine and quinoline ethene derivatives are described, and these compounds will now be considered in detail. Each series has been confined to a separate section for the sake of clarity, and each of these sections is, as far as ...

The low-frequency vibrational spectra of the 1 : 1 acridine-bromine and 2 : 3 acridine-iodine complexes

open access: yes, 1978
The low-wavenumber (<400 cm-1) vibrational spectra of the 1 : 1 acridine-bromine complex, the 2 : 3 acridine-iodine complex, and tetrabutylammonium pentaiodide have been measured, and these indicate that the bromine complex is the molecular compound ...

[(acridine)BCl2]+: A Borenium Cation That Is a Strong Boron- and Carbon-Based Lewis Acid

open access: yes, 2016
[(acridine)­BCl2]­[AlCl4] was synthesized by halide abstraction from (acridine)­BCl3 with AlCl3. The hydride ion affinity of the C9 position in [(acridine)­BCl2]+ was calculated to be 14 kcal mol–1 greater than that at boron.

Synthetic Modifications of a Pb2+-Sensor Acridono-Crown Ether for Covalent Attachment and Their Effects on Selectivity

open access: yesMolecules
Because of environmental impact, there is a great need for chemosensors, especially for toxic heavy metals such as lead. The conventional instrumental analytical techniques rarely provide an available real-time sensing platform, thus the development of ...
