Total spontaneous resolution of nine-coordinate complexes

Rational Design of Lanthanoid Single‐Ion Magnets: Predictive Power of the Theoretical Models

“…The compounds were characterised by FT‐IR spectroscopy (Figures S1 and S2 in the Supporting Information), X‐ray power diffraction and single‐crystal X‐ray diffraction. The unit cell parameters are coincident with the ones reported previously (Figures S3 and S4).…”

“…The crystal structures of both compounds have been previously described in detail . Both compounds undergo spontaneous resolution on crystallisation.…”

“…It has been reported that the formation of hydrogen bonds involving BF 4 − anions could be essential in the packing of the homochiral complexes, resulting in the spontaneous resolution. The coordination geometry around the lanthanide ion is practically identical for both DyODA and ErODA.…”

“…The syntheses of DyODA and ErODA were performed by following a previously described procedure . All reagents were commercially purchased and used without any further purification.…”

Absolute Asymmetric Synthesis of Enantiopure Organozinc Reagents, Followed by Highly Enantioselective Chlorination

“…We have recently reported total spontaneous resolution of a number of different compounds, for example, organometallic reagents, [16][17][18][19] an aluminium phenoxide complex, [20] a coordination network, [21] a conformationally chiral sulfide, [22] an octanuclear organozinc complex, [23] a helical coordination polymer, [24] and several coordination compounds for example, five-, [25] seven- [26] and nine-coordinate complexes. [27] The stereochemical lability, which is required for total spontaneous resolution to occur, means that the optically active product will racemize on dissolution. The optical activity may, however, be fixed through a reaction that yields a stereochemically inert product.…”
