Selective Ruthenium-Catalysed Functionalisation Reactions and ROMP of exo-Norbornene-Based Organosilicon Boronic Esters

The ruthenium-catalysed silylative coupling (SC) reaction is a useful method for obtaining selectively functionalised organosilicon compounds, which have a wide range of applications in organometallic and organic chemistry. It is possible to prepare such compounds with norbornene matrices, which can be used for ring-opening metathesis polymerisation (ROMP) in the synthesis of linear-type polymers. Herein, we present a method for the synthesis of the aforementioned matrices by a condensation reaction between diol and vinylphenylboronic acids. Furthermore, these compounds were subsequently modified by SC reaction and polymerised by ROMP. To assess the possibility of using styryl-based silyl-derived monomers as building blocks in further organic transformations, the process of bromodesilylation was also investigated. We would also like to perform a comparative study on the selectivity of hydrosilylation and silylative coupling processes in the case of discovered materials.
