N-heterocyclic phosphinidyne ligands

咪唑啉-2-亚基型的N-杂环卡宾（NHC）将用于制备卡宾-次膦加合物（NHC）PSiMe 3和（NHC）PH以及类似的砷、锑和铋化合物。利用这些原料，我们将合成混配型和异双核二卡宾双元素配合物（NHC）EE '（NHC'）（E = P，As，Sb; E' =主族3-5的元素），并研究它们的反应活性。

N-Heterocyclic carbenes (NHC) of the imidazolin-2-ylidene-type will be employed for the preparation of carbene-phosphinidene adducts (NHC)PSiMe3 and (NHC)PH and of analogous arsenic, antimony, and bismuth compounds. With these starting materials at hand, heteroleptic and heterobinuclear dicarbene-dielement complexes (NHC)EE‘(NHC’) (E = P, As, Sb; E‘ = element from main groups 3–5) will be synthesized and their reactivity will be studied.
