Darstellung und Zerfall von tertiären Hyponitriten

1971

Dicumylhyponitrit (1a), substituierte Dicumylhyponitrite (1b1f) (p-Br, p-Cl, p-CH3, m-CH3, p-CH3O), Bis-[1.1-diphenyl-athyl]-hyponitrit (1h) und Bis-[1.1-dimethyl-pentyl]-hyponitrit (1g) wurden dargestellt. Die tertiaren Hyponitrite zerfallen bereits rasch bei-40 in Stickstoff und freie Alkoxyradikale, die dann zu den entsprechenden Alkoholen und Ketonen weiter reagieren. Die relativen Reaktivitaten von tert.-Butyloxy-und Cumyloxyradikalen hinsichtlich Wasserstoffabstraktion und β-Spaltung wurden fur verschiedene Losungsmittel bestimmt; Cumyloxyradikale neigen starker zur β-Spaltung als tert-Butyloxyradikale. Die freien Alkoxyradikale konnen Polymerisations- und Autoxydationsreaktionen init…

Kinetik und Radikalausbeute beim Zerfall tertiärer Hyponitrite

1971

Der thermische Zerfall von Dicumylhyponitrit (1a) ist eine Reaktion erster Ordnung mit einer Aktivierungsenthalpie von 27.3 keal/Mol und einer Aktivierungsentropie von 8.5 cal/Mol·Grad in Isooctan. Die Radikalausbeute fur 1a betragt 84%, fur Di-tert.-butylhyponitrit 92%. Die Zerfallskonstanten substituierter Dicumylhyponitrite gehorchen bei Verwendung der σ+-Werte der Hammett-Beziehung mit σ=+ +0.34. Kinetic and Radical Efficiency for the Decomposition of Tertiary Hyponitrites The thermal decomposition of dicumylhyponitrite (1a) is a first order reaction with an activation enthalpy of 27.3 kcal/mole and an activation entropy of 8.5 e. u. in isooctane. The efficiency of radical formation is …

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition) 1

2021

Contains fulltext : 232759.pdf (Publisher’s version ) (Closed access) In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to…
