✦ Synopsis

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.
