Abstract

Density functional theory calculations and 2D 1H–13C HETCOR solid state NMR spectroscopy prove that CO2 can be used to probe, by its own reactivity, different types of N-donor surface ligands on SBA15-supported ZrIV hydrides: [([triple bond, length as m-dash]Si–O–)([triple bond, length as m-dash]Si–N[double bond, length as m-dash])[Zr]H] and [([triple bond, length as m-dash]Si–NH–)([triple bond, length as m-dash]Si–X–)[Zr]H2] (X[double bond, length as m-dash]O or NH). Moreover, [([triple bond, length as m-dash]Si–O–)([triple bond, length as m-dash]Si–N[double bond, length as m-dash])[Zr]H] activates CO2 more efficiently than the other complexes and leads to the formation of a carbimato Zr formate.
