N. Saracoglu et M. Balci, Synthesis of a new system containing a pyramidalized double bond: Lack of reactivity of a strongly protected pyramidalized double bond, HELV CHIM A, 84(3), 2001, pp. 707-714
The chemical reactivity of syn-3 was investigated. The experimental results
showed that the central double bond of this system is inert toward chemica
l reactions. To determine the reactivity of this central double bond. we sy
nthesized syn- and anti-7 and recorded their photoelectron spectra. Low fir
st-ionization potentials of syn- and anti-7 (7.6 eV) dearly indicated that
these compounds should be highly reactive.
