Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

A new type of structure in sodium amide ring chemistry: crystal structure of [PhCH2(Me)NNa(tmeda)]2 showing a buckled, rather than the normal planar, (NNa)2 cyclic ring, with a cisoid, rather than the normal transoid, arrangement of amido-substituents (tmeda = tetramethylethylenediamine)

Abstract

The red crystalline complex [PhCH2(Me)NNa(tmeda)]2, synthesised from equimolar proportions of PhNa, the secondary amine PhCH2(Me)NH and the Lewis base tmeda (tetramethylethylenediamine, Me2NCH2CH2NMe2), has been structurally identified by X-ray diffraction studies, which reveals a new type of structure based on a buckled (NNa)2 dimeric ring with a cisoid arrangement of amido-substituents.
