The use of ball mills enabled the efficient mechanosynthesis of a variety of N-aryl,N-alkyl imidazolium salts and of corresponding NHC silver(I) complexes. Transmetalation with ruthenium via mechanochemistry allowed the rapid access (from 1.5 min to 1 h) to complexes having a similar structure to Noels-type precatalysts. Evaluation of the complexes in the ring-opening metathesis polymerization of norbornene in different solvent, including nontoxic ones, showed a high catalytic activity for one of them, comparable to that of the Noels catalyst.

Noels型NHC-钌配合物的机械合成及其在开环易位聚合中的应用

球磨机的使用使各种N-芳基,N-烷基咪唑鎓盐和相应的NHC银(I)络合物的有效机械合成成为可能。钌通过机械化学进行重金属化可以快速进入(从1.5分钟到1小时)到与Noels型预催化剂具有相似结构的络合物。评估降冰片烯在不同溶剂(包括无毒溶剂)中的开环易位聚合反应中的配合物,发现其中一种与Noels催化剂相比具有很高的催化活性。
