Hj. Lindner et K. Hafner, SOLID-STATE DIMERIZATION OF A 5-VINYLIDENE-CYCLOPENTADIENE, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 276, 1996, pp. 339-348
The kinetically stabilized 1.3-di-t-butyl-5-vinylidenecyclopentadiene
(1) dimerizes in a thermal solid state reaction to the tetraquinane de
rivative 6. A reaction mechanism for this topochemically controlled re
action is proposed on the basis of results of X-ray analyses and semie
mpirical calculations.
