文献中X-type ligand和L-type ligand是什么样的配体?

宝宝,把你的文献必要的那段贴出来.Alternatively,unligated transition metal salts are also effective catalysts for reactions triggered by the π-activation; however,enantioselective cycloisomerization reactions employing complexes lacking chiral Sample Text remain scarce.Having realized the potential of chiral phosphates as counterions in the gold(I)-catalyzed enantioselective transformations,we envisioned the utility of this motif in the form of an anionic Sample Text for electrophilic transition metal catalysis.chem宝宝(站内联系TA)Originally posted by amber369 at 2011-06-24 06:19:53:
