Abstract

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