Abstract:
Reaction of carbene-stabilized disilicon L:Si═Si:L (L: = :C{N(2,6-Pr(i)(2)C(6)H(3))CH}(2), 1) with BH(3)·THF results in facile cleavage of the silicon-silicon double bond and the formation of two quite different "push-pull" stabilized products with borane- and carbene-coordinated silylene moieties: 2, containing a parent silylene (:SiH(2)); and 3, containing a unique three-membered cyclosilylene.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
