Heterogeneous‐Gold‐Catalyzed Acceptorless Cross‐Dehydrogenative Coupling of Hydrosilanes and Isocyanic Acid Generated in situ from Urea

Abstract

Support structure: In the presence of gold nanoparticles supported on alumina (Au/Al2O3), various hydrosilanes can be converted into the corresponding silyl isocyanates using urea as an isocyanate source. The observed catalysis is truly heterogeneous, and the retrieved Au/Al2O3 catalyst can be reused several times without any loss of its high catalytic performance.
