Metal as Source of Chirality in Octahedral Complexes with Tripodal Tetradentate Ligands.
The challenging control of the absolute configuration of chiral-at-metal complexes is efficiently achieved using the tripodal tetradentate ligand L. The optical resolution of rac-[RhCl(κC,N,N′,P-L)] mediated by (S)-α-phenylglycine provides access to enantiopure complexes of general formula [Rh(κC,N,...

The optical resolution of rac-[RhCl(κC,N,N′,P-L)] mediated by (S)-α-phenylglycine provides access to enantiopure complexes of general formula [Rh(κC,N,N′,P-L)A- (Solv)][SbF] that enantioselectively catalyze the Diels- Alder reaction between methacrolein and HCp with enantiomeric ratio of up to >99/1. The nature of the active species, the origin of the enantioselectivity and mechanistic details are disclosed by means of NMR spectroscopy and DFT studies. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2018 holdings: @attributes: islocal: N |
