“…Within the diverse group of organophosphorus compounds phospholes play a prominent role [ 1 , 2 ]. Owing to their low HOMO-LUMO gap these five membered heterocycles show pronounced luminescence in form of fluorescence making them excellent materials for a wide range of applications [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ].…”

Asymmetrically Substituted Phospholes as Ligands for Coinage Metal Complexes

2022

A series of coinage metal complexes asymmetrically substituted 2,5-diaryl phosphole ligands is reported. Structure, identity, and purity of all obtained complexes were corroborated with state-of-the-art techniques (multinuclear NMR, mass spectrometry, elemental analysis, X-ray diffraction) in solution and solid state. All complexes obtained feature luminescence in solution as well as in the solid state. Additionally, DOSY-MW NMR estimation experiments were performed to achieve information about the aggregation behavior of the complexes in solution allowing a direct comparison with their structures observed in the solid state.

“…Dibenzophospholes and fused heteroaromatic derivatives have attracted increasing interest for their applications in organic optoelectronic materials, catalysis and bioimaging . Chiral versions of dibenzophospholes or derivatives have been developed and proved to be suitable ligands , or Lewis-bases in asymmetric catalysis or organocatalysis, respectively. In these cases, the chirality is located either on the carbon backbone or on the P atom, or both, as in the examples 1 – 7 presented in Figure .…”

An enantioselective synthesis of a new class of benzophosphole-based heterocycles bearing a fused triazole ring with enantioselectivities of ≤99% is reported. The key steps of the synthesis are based on an innovative stereospecific phosphinyl N → O migration of aminophosphine-boranes into phosphinites, followed by an intramolecular cyclization. Five X-ray structures of P-chirogenic triazolobenzophospholes and a gold(I) complex were established, for assigning absolute configurations, the stereochemistry of the reactions, and the placement of the triazole substituent at the syn position of the P center.
