The invention relates to highly active and selective catalysts for alkyne metathesis. In one aspect, the invention includes a multidentate organic ligand wherein one substrate-binding site of the metal center is blocked. In another aspect, the invention includes N-quaternized or silane-based multidentate organic ligands, capable of binding to metals. In yet another aspect, the invention includes N-quaternized or silane-based multidentate catalysts. The catalysts of the invention show high robustness, strong resistance to small alkyne polymerization and significantly enhanced catalytic activity compared to their corresponding non-quaternized or non-silane-based multidentate catalyst analogues.
该发明涉及用于炔烃交换反应的高活性和选择性催化剂。在一个方面,该发明包括一种多齿有机配体,其中金属中心的一个底物结合位点被阻塞。在另一个方面,该发明包括N-季铵化或硅基多齿有机配体,能够与金属结合。在另一个方面,该发明包括N-季铵化或硅基多齿催化剂。该发明的催化剂表现出高稳定性,对小炔烃聚合具有很强的抵抗力,并且与其对应的非季铵化或非硅基多齿催化剂类似物相比,具有显着增强的催化活性。
