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.
载体结构:在
金纳米颗粒负载在氧化铝(Au / Al 2 O 3)上的情况下,可以使用
尿素作为
异氰酸酯源将各种氢
硅烷转化为相应的甲
硅烷基
异氰酸酯。观察到的催化确实是非均相的,并且回收的Au / Al 2 O 3催化剂可以重复使用几次,而不会损失其高催化性能。
