The [1.1.1]propellane radical cation 1(•+), generated by radiolytic oxidation of the parent compound in argon and Freon matrices at low temperatures, undergoes a spontaneous rearrangement to form the distonic 1,1-dimethyleneallene (or 2-vinylideneallyl) radical cation 3(•+) consisting of an allyl radical substituted at the 2-position by a vinyl cation. In similar matrix studies, it is found tha...
In 1915, just three years after the discovery of X-ray diffraction by Von Laue, Peter Debye noted that “the scattering from light atoms should get more attention, since along this way it should be possible to determine the arrangement of electrons in crystals”. Debye!s statement preceded the development of quantum mechanics and Born!s definition of electron probability distribution, but correct...
