Abstract

The synthesis of 1-[2-(3-{7-oxabicyclo[4.1.0]heptyl} 1,1,3,3-tetramethyl-disiloxane (Mono), which is a key intermediate for the synthesis of monomers applied for photopolymer systems based on the cationic ring opening polymerization, was studied. Mono was successfully synthesized by the hydrosilylation reaction of 4-vinyl-1-cyclohexene 1,2-epoxide (VCHO) with an excess amount of 1,1,3,3-tetramethyldisiloxane (TMDS) in the presence of a Speier catalyst. The structure and the purity of Mono were characterized by FT-IR, $^1H-NMR$, and $^{29}Si-NMR$. The optimum conditions for the hydrosilyation reaction were found to be 1:4 molar ratio of VCHO to TMDS and 5 ppm of the catalyst at the temperature of $55^{\circ}C$.
