T. Nishinaga et al., EFFECTS OF SUBSTITUENTS ON SILICON UPON THE RING INVERSION OF SILEPINS ANNELATED WITH BICYCLO[2.2.2]OCTENE FRAMEWORKS, Chemistry Letters, (3), 1998, pp. 269-270
The energy barrier for ring inversion of the silepin annelated with bi
cyclo[2.2.2]octene was found to decrease as the electronegativity of s
ubstituents on silicon increases.
