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.
