Traces of Elements in the Electrochemical Reductive Amination of Acetone: Uncovering Bi as Substitute for Pb

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.
This study investigates the impact of various p‐block element impurities in the electrochemical reductive amination and reveals with Bi a less toxic alternative for Pb. The utilization of Bi as additive was further optimized by studying the impact of additive concentration, reaction temperature, and cathode material on amine yield, offering new ...

Ethylamine [MAK Value Documentation, 2019]

open access: yes, 2019
The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated ethylamine [75‐04‐7], considering all toxicological endpoints. The critical effect is irritation of the nasal epithelium of rats with a NOAEC of 100 ml/m3 in a 24‐week inhalation study.

A comparison of the effects of no radrenaline, adrenaline and some phenylephrine derivatives on alpha-, betal " and beta2- adrenergic receptors [PDF]

open access: yes, 2017
The possibility of two types of beta-adrenergic receptors is supported by the results presented. It is shown that the phenylephrine group of compounds have more pronounced affinities towards the beta,-(cardiac) adrenergic receptors than towards the beta,-
