Abstract

The silica-supported Zr(IV) dihydride [([triple bond, length as m-dash]SiO)2ZrH2] reacts quickly and completely with methane to yield [([triple bond, length as m-dash]SiO)2ZrMe2] through the intermediate [([triple bond, length as m-dash]SiO)2ZrHMe], while its monohydride analogue [([triple bond, length as m-dash]SiO)3ZrH] yields the monomethylated product [([triple bond, length as m-dash]SiO)3ZrMe] slowly and incompletely.
