Preparation of the 15-membered cycle (E,E,E)-1,6,11-tris[(2,4,6-triisopropylphenyl)sulfonyl]-1,6,11-triazacyclopentadeca3,8,13-triene (8) is reported. This cyclic triolefin forms a stable Pd0 complex 9 which catalyzes several cross-coupling reactions and can be recovered. Anchoring to a polystyrene framework affords a solid version of the catalyst, which is recovered by simple filtration and reused
15 元环 (E,E,E)-1,6,11-tris[(2,4,6-triisopropylphenyl)sulfonyl]-1,6,11-triazacyclopentadeca3,8,13-triene (8 ) 报道。该环状三烯烃形成稳定的 PdO 络合物 9,该络合物催化多种交叉偶联反应并可回收。锚定在聚苯乙烯框架上提供了一种固体形式的催化剂,通过简单的过滤回收并重复使用而不会损失催化活性。
