Reactivity of polypnictogen complexes towards nucleophiles and their subsequent chemistry

多磷配体络合物的亲核官能化是构建新型功能磷配体的基本合成工具，在将它们从过渡金属中移除后，可以生成不对称取代的膦。该项目旨在对磷配体络合物进行亲核优化和亲电多样化，以消除作为对映体化合物的不对称取代膦化合物。鉴于ASN和SBN配体络合物的亲核功能化和亲电多样化，将进行大量的基础研究，以开发不同官能化的砷和苯乙烯配体的新途径，并从过渡金属中去除这些配体，以获得分别不对称取代或取代的不对称官能化的砷和苯乙烯的简便合成途径。此外，通过双金属活化袋，白磷和黄砷的新型亲核官能化也将被开发。

Nucleophilic functionalizations of polyphosphorus ligand complexes are essential synthetic tools to build novel functional phosphorus ligands and, after their removal from the transition metal, to generate e.g., asymmetrically substituted phosphines. The project aims at the nucleophilic optimization and electrophilic diversification of phosphorus ligand complexes to remove asymmetrically substituted phosphines as enantiopure compounds. Substantial fundamental research will be conducted in view of the nucleophilic functionalization and the electrophilic diversification of Asn and Sbn ligand complexes, respectively, to develop new pathways to differently functionalized arsine and stibine ligands and to remove these as well from the transition metal in order to obtain facile synthetic pathways to asymmetrically substituted or divers functionalized arsines and stibines, respectively. Further, new types of nucleophilic functionalizations of white phosphorus and yellow arsenic, respectively, by a bimetallic activation pocket are to be developed.
