The principle silane monomers have traditionally been methyl and phenyl, and hitherto cycloaliphatic silane monomers have not been reported because of steric hindrance of the cyclic alkenes. The route used in the preparation of the cycloaliphatic substitution was taken due to the difficulties of reaction the internal alkene with the available silane group.
In the Stille reaction, a stannylated alkene and an electrophile, such as an aromatic halide or triflate are reacted in the presence of a palladium catalyst.
Oligomeric alkene monoamine for instance was prepared by epoxidizing an oligomeric alkene to form an oligomeric alkene aldehyde and an oligomeric alkene monoamine, which is obtained over oxime.
It demonstrates that the addition of transition metal salts decreases the alkane content and increases both the alkene content and the alkenes/alkanes ratio.
