• A Class of Readily Tunable Planar‐Chiral Cyclopentadienyl Rhodium(III) Catalysts for Asymmetric C–H Activation

  rhodium(III) (CpRhIII) complexes are powerful catalysts for promoting asymmetric C−H activation reactions. At present, their preparations mainly rely on the development of various chiral cyclopentadienyl (Cp) ligands by linking or embedding the Cp motif to or into a certain chiral backbone. In contrast, development of planar-chiral only CpRhIII catalysts bearing non-chiral Cp ligands remains a formidable

  手性半夹心环戊二烯基铑 (III) (CpRh III ) 配合物是促进不对称 C-H 活化反应的强大催化剂。目前，它们的制备主要依赖于通过将Cp基序连接或嵌入到某个手性骨架上来开发各种手性环戊二烯（Cp）配体。相比之下，迄今为止，开发仅具有非手性 Cp 配体的平面手性 CpRh III催化剂仍然是一项艰巨的挑战，并且很大程度上尚未开发。本文描述了一类易于调节的纯平面手性 CpRh III催化剂及其在不对称 C-H 活化反应中的应用。
• Multifunctional Cyclopentadienes as a Scaffold for Combinatorial Bioorganometallics in [(η ⁵ ‐C ₅ H ₂ R ₁ R ₂ R ₃ )M(CO) ₃ ] (M=Re, ^99m Tc) Piano‐Stool Complexes

  AbstractMultifunctional cyclopentadiene (Cp) ligands and their rhenium and 99mTc complexes were prepared by a versatile synthetic route. The properties of these Cp ligands can be tuned on demand, either during their synthesis (variation of R1) or through post‐synthetic functionalization with two equal or different vectors (V1 and V2). Variation of these groups enables a combinatorial approach in the synthesis of bioorganometallic complexes. This is demonstrated by the preparation of Cp ligands containing both electron‐donating and electron‐withdrawing groups at the R1 position and their subsequent homo‐ or heterofunctionalization with biovector models (benzylamine and phenylalanine) under standard amide bond‐formation conditions. All ligands can be coordinated to the fac‐[Re(CO)3]+ and fac‐[99mTc(CO)3]+ cores to give tetrafunctional complexes in straightforward and functional‐group‐tolerant procedures. The 99mTc complexes were prepared in one step, in 30 min, and under aqueous conditions from generator‐eluted [99mTcO4]−.
