construction of a robust chiral porous polymer (JH‐CPP) embedded with the Jørgensen–Hayashi catalyst (JH) has been successfully achieved for highly efficient heterogeneous organocatalysis. The high BET surface area, wide openings and interconnected nanopores of JH‐CPP increase the accessibility of catalytic sites and as such the catalyst shows excellent activity in catalyzing the asymmetric Michael addition
唯一的办法就是向上!已经成功实现了嵌入约恩根森-早石催化剂(JH)的坚固的手性多孔聚合物(JH-CPP)的“自下而上”构造,可实现高效的多相有机催化。JH-CPP的高BET表面积,宽阔的开口和相互连接的纳米孔增加了催化部位的可及性,因此,该催化剂在催化不对称迈克尔加成反应方面显示出出色的活性(请参阅方案)。
