Research of the Formation of Regularities Siloxane Norbornene Derivatives by Thermal Diels-Alder Reaction

The methods of chromatography-mass spectrometry and 1H NMR-spectroscopy were used to study the reaction between dicyclopentadiene and vinyltriethoxysilane. The main reaction products are exo- and endo-isomers bicycle [2.2.1] hept-5-en-2-yl(triethoxy)silane. The overall yield of isomers is 55% of the load components. Co-products are the alkoxysilyl derivatives of dicyclopentadiene. Also the authors of the article paid attention to the problems of the time and temperature reaction, and ratios of starting components on chemical yield.
