Helicity Induction in Helicate Self‐Organisation from Chiral Tris(bipyridine) Ligand Strands

Zarges, Wolfgang, Hall, Jonathan, Lehn, Jean‐Marie, Bolm, Carsten·1991·Helvetica Chimica Acta

Abstract

The chiral tris, and pentakis(bipyridine) ligand strands 3a and 4 were synthesised, each in optically pure form with (S,S)‐configuration. Ligand 3a yielded substituted double‐helical metal complexes, derived from the parent trihelicate structure 2, with Cu I and Ag I ions. The spectral data, in particular the 1 H‐NMR spectra and the large positive Cotton effect, indicate that helicate formation occurs with very high induction of helicity. Together with consideration of the steric effects in the two possible helical diastereoisomers (P)‐1 and (M)‐1 that may be formed, the data favour the preferential generation of the right‐handed double helicate (P)‐1 from the tris(bipyridine) strand 3a of(S,S)‐configuration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
