Coordination chemistry of gold catalysts bearing eight different ligands [L=PPh3, JohnPhos (L2), Xphos (L3), DTBP, IMes, IPr, dppf, S‐tolBINAP (L8)] has been studied by NMR spectroscopy in solution at room temperature. Cationic or neutral mononuclear complexes LAuX (L=L2, L3, IMes, IPr; X=charged or neutral ligand) underwent simple ligand exchange without giving any higher coordinate complexes. For
已通过NMR光谱在室内溶液中研究了带有八种不同配体[L = PPh 3,JohnPhos(L2),Xphos(L3),DTBP,IMes,IPr,dppf,S- tolBINAP(L8)的金催化剂的配位化学温度。阳离子或中性单核复合物LAuX(L = L2,L3,IMes,IPr; X =带电或中性配体)进行简单的配体交换而没有给出任何更高的配位络合物。对于L2 AUX测定以下配体强度系列:MeOH«hex-3-炔
