Chiral Diphosphine Ligands and New Reactions of Organozinc Compounds
Using the [2,3]-sigmatropic rearrangement of chiral allylic diarylphosphinites, a number of new enantiopure 1,3-diphoshine ligands were prepared. Enzymatic kinetic rezolution of allylic alcohols was used for the preparation of enantiopure starting materials. Several new reactions of organozinc compounds, i. e. new thiolation method, Ni-catalyzed cross-coupling reactions and a method of preparation of alkylzinc bromides from the corresponding alkylbromides were developed.
