The thermo-labile triazenide Na[tBu3SiNNNSiMe3] was prepared by the reaction of Me3SiN3 with Na(thf)2[SitBu3] in pentane at -78 °C. Treatment of Na[tBu3SiNNNSiMe3] with an excess of carbon dioxide in pentane at -78 °C yielded the imido carbonate (tBu3SiO)(Me3SiO)C[double bond, length as m-dash]N-SitBu3 and the carbamine acid (tBu3SiO)CONH2 along with other(More)
Two-dimensional (2D) systems with continuous symmetry lack conventional long-range order because of thermal fluctuations. Instead, as pointed out by Berezinskii, Kosterlitz and Thouless (BKT), 2D systems may exhibit so-called topological order driven by the binding of vortex-antivortex pairs. Signatures of the BKT mechanism have been observed in thin films,(More)
