Abstract:
We report the series of G1 and G1.5 dendritic systems with mono-T8 SQs and DDSQ as specific types of dendron and dendrimer cores, respectively. The trivinyl- and tri(chloromethyl)-derivatives were obtained via hydrolytic condensation followed by the hydrosilylation reaction, optimized to yield selectively β-products. Their structures were confirmed by spectroscopic and XRD analyses. It is the first example of double-decker SQs used as cores for the construction of a low generation of dendrimer featuring specific dumbbell frameworks expanding in two or four directions.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...

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...
