Direct observation of reaction intermediates for a well defined heterogeneous alkene metathesis catalyst

Grafting of [W(≡NAr)(=CHtBu)(2,5-Me(2)NC(4)H(2))(2)] on a silica partially dehydroxylated at 700°C (SiO(2- (700))) generates the corresponding monosiloxy complex [(≡SiO)W(≡NAr)(=CHtBu)(2,5-Me(2)NC(4)H(2))] as the major species (≈90%) along with [(≡SiO)W(≡NAr)(CH(2)tBu)(2,5-Me(2)NC(4)H(2))(2)], accor...
