coordinative immobilization of [Cp*IrCl2]2 on poly(4-vinylpyridine), was proven to be an efficient heterogeneous autotandem catalyst for synthesizing quinazolinones via selective hydration/acceptorless dehydrogenative coupling from o-aminobenzonitriles. Furthermore, the synthesized catalyst was recycled five times without an obvious decrease in the catalytic activity.
通过将[Cp * IrCl 2 ] 2配位固定在聚(4-乙烯基吡啶)上设计和合成的线性有机聚合物负载的铱络合物Cp * Ir @ P4VP被证明是一种有效的异质串联催化剂通过邻氨基苄腈的选择性水合/无受体脱氢偶联合成喹唑啉酮。此外,将合成的催化剂循环使用五次,而催化活性没有明显降低。
