title: Well-defined single-site monohydride silica-supported zirconium from azazirconacyclopropane.
abstract: The silica-supported azazirconacyclopropane ≡SiOZr(HNMe2)(η(2)-NMeCH2)(NMe2) (1) leads exclusively under hydrogenolysis conditions (H2, 150 °C) to the single-site monopodal monohydride silica-supported zirconium species ≡SiOZr(HNMe2)(NMe2)2H (2). Reactivity studies by contacting compound 2 with ethylene, hydrogen/ethylene, propene, or hydrogen/propene, at a temperature of 200 °C revealed alkene hydrogenation.
