New air-stable ruthenium complex 1, bearing the dibenzobarrelene-based cooperating ligand, was synthesized in 96% yield and fully characterized. The examination of its coordination chemistry revealed that the ruthenium center in 1 is slightly distorted from octahedral geometry, and 31P NMR is consistent with the formation of trans-spanned pincer complexes bearing strongly bent dibenzobarrelene-based
带有二苯并barrelene基的配合配体的新的空气稳定的钌络合物1以96%的收率合成并得到了充分表征。对其配位化学的检查表明,钌中心在1中略微偏离了八面体的几何形状,并且31 P NMR与带有强弯曲的基于二苯并barrelene的配体的跨跨钳形配合物的形成是一致的。在醇的无受体脱氢和醇与胺的无受体脱氢偶联中检查了新配合物的催化活性。
