Cross-metathesis of vinyl-substituted linear and cyclic siloxanes with olefins in the presence of Grubbs catalysts
چکیده انگلیسی

Efficient cross-metathesis (CM) of linear and cyclic vinyl-substituted oligosiloxanes with selected olefins in the presence of Grubbs type ruthenium alkylidene complexes is described. Treatment of styrene or 4-substituted styrenes with vinyl group at siloxane skeleton results in the formation of respective cross-metathesis products with good yields and selectivities.

The cross-metathesis of vinyl-substituted linear and cyclic oligosiloxanes with styrenes, alkenes and selected allyl derivatives proceeds efficiently in the presence of Grubbs catalysts. Respective products have been obtained with high yields and selectivities.Figure optionsDownload as PowerPoint slide
