The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Direct observation and characterisation of 3-azido-2H-azirines: postulated, but highly elusive intermediatesWeigand, Kevin, Singh, Neeraj, Hagedorn, Manfred, Banert, Klaus 29 March 2017 (has links) (PDF)
For the first time, successful synthesis of an unknown class of compounds, 3-azido-2H-azirines, which are implicated as highly reactive intermediates in the thermolysis of the corresponding 1,1-diazidoethenes, has been performed. These elusive heterocycles have been detected and characterised by low-temperature NMR and in situ IR spectroscopy. Even the parent compound, 3-azido-2H-azirine, has been observed via low-temperature photolysis of 1,1-diazidoethene, as a highly reactive species with a half-life period of only 12 min at −40 °C. / Dieser Beitrag ist aufgrund einer (DFG-geförderten) Allianz- bzw.
