《Synthesis and Metathesis Polymerization of New Monomer 7-Trimethylsilyltricyclo[4.2.2.02,5]deca-3,9-diene》 was written by Zhigarev, V. A.; Gringolts, M. L.; Filatova, M. P.; Finkelshtein, E. Sh.. SDS of cas: 172222-30-9This research focused ontrimethylsilyltricyclo decadiene preparation metathesis polymerization characterization. The article conveys some information:
The reaction of 1,3,5,7-cyclooctatetraene with silicon-substituted ethylenes has been studied for the first time. It is shown that vinyltrimethylsilane is inactive in the reaction, and vinyltrichlorosilane forms 7-trichlorosilyltricyclo[4.2.2.02,5]deca-3,9-diene in up to 12% yield. A new silicon-substituted monomer 7-trimethylsilyltricyclo[4.2.2.02,5]deca-3,9-diene containing 92% of the endo-isomer has been synthesized by methylation of the chloroadduct. The metathesis polymerization of the final monomer mediated by the Grubbs Ru catalysts of the first and second generations is studied. A new poly(7-trimethylsilyltricyclo[4.2.2.02,5]deca-3,9-diene) containing a bulky bicyclic fragment and predominantly trans-double bonds in the main chain (up to 94%) is obtained in 90-96% yields. The polymer is characterized by the highest glass transition point (187°C) in the series of monotrimethylsilyl-substituted polynorbornenes. The double bonds present in the monomer unit open up prospects for further modification. In addition to this study using Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, there are many other studies that have used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9SDS of cas: 172222-30-9) was used in this study.
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is the first metathesis catalyst to be widely used in organic synthesis. It is useful for acyclic diene metathesis polymerization (ADMET), Ring-Opening Metathesis Polymerization (ROMP) of strained cyclic olefins, ring opening metathesis (ROM), and so on.SDS of cas: 172222-30-9
