N2 - At 50°C already the hydrogenolysis of neopentane, isobutane, and propane is catalyzed by the silica‐supported zirconium hydride [( ⦠ SiO)3ZrH]. The reaction selectively produces methane together with isobutane, propane, and ethane, respectively. The activity is attributable to the high electrophilicity of the 8‐electron do complex and is not observed for nonsupported, discrete zirconium hydrides. Moreover, the attachment to the support prevents a bimolecular deactivation.
