One-Step Selective Method for the Synthesis of Silicon-Containing exo-Norbornenes

A one-step selective method for the synthesis of exo isomers of silicon-containing norbornenes by hydrosilylation of norbornadiene-2,5 with non-activated silanes in the presence of a Pd catalyst and bulky ligands has been developed. This approach leads to the formation of exo isomers only. The absence of stages of alkylation with organometallic reagents and photochemical rearrangement makes this approach attractive for directed design and synthesis of new polymeric materials showing required properties.
