A linear-organic-polymer-supported iridium complex CpIr@P4VP, which is designed and synthesized by the coordinative immobilization of [CpIrCl] on poly(4-vinylpyridine), was proven to be an efficient heterogeneous autotandem catalyst for synthesizing quinazolinones via selective hydration/acceptorless dehydrogenative coupling from -aminobenzonitriles. Furthermore, the synthesized catalyst was recycled five times without an obvious decrease in the catalytic activity.
一种线性有机聚合物负载的铱配合物CpIr@P4VP，它是通过[CpIrCl]与聚（4-乙烯基吡啶）的配位固定化设计合成的，被证明是一种高效的多相自串联催化剂，可通过从氨基苯腈选择性水合/无受体脱氢偶联合成喹唑啉酮。此外，合成的催化剂循环使用了五次，催化活性没有明显下降。
