The N-isopropyl imine of lithioacetaldehyde, I, was found to exist as a 50:50 mixture of two isomers, as seen below -20 deg C by 1H and 13C NMR.Comparison of the population ratio and spectral characteristics of the isomers of this and related lithiated im

The single-electron oxidation of tetraisopropyltetrazene by the advantageous, oxygen-free SbCl5/H2CCl2 redox system yields dark-red crystals of tetraisopropyltetrazenium hexachloroantimonate.Their structure determination at temperatures of 100, 200, and 293 K, the first one of a 2-tetrazene radical cation, proves a planar skeleton C2N-N=N-NC2(.+) with nearly identical NN bond lengths.The reaction of tetraisopropyltetrazene with surplus SbCl5 yields the N2 elimination product isopropylisopropylideneammonium haxachloroantimonate, which also has been crystallized and structurally characterized.Due to the conformation of the C3 subunits perpendicular to each other, the cation (H3C)2HC-HN(+)=C(CH3)2 is extremely overcrowded as demonstrated by an angle CNC of 129 deg.In addition, the thermal decomposition of tetraisopropyltetrazene in the gasphase has been analyzed PE-spectroscopically, its first and second oxidation potentials have been determined cyclovoltammetrically, and the ESR signal pattern of its radical in solution has been recorded and assigned.Based on the experimental data, a possible pathway for the oxidative decomposition of the title compound is discussed. - Key Words: Tetrazene, tetraalkyl-, oxidation / Photoelectron spectra / ESR spectra / Calculations, AM1
