eng	Structure and possible application of chiral B-enaminone complexes	The topic covering carboranes has attracted a significant interest nowadays chemistry due to remarkable reactivity and possible wide range of applications starting from polymerization reactions to various organic transformations. On the contrary, β-enaminone (BEN) may be classified among the most widespread spectator systems which can stabilize metal centers and thus form six membered metallacycles. The central fragment consists of NC3O entity and renders space for variation of its substituents with tunable steric demand. The combination of carborane and BEN parts forming "chiral" vicinity of metal in one specie open new area of coordination chemistry and could contribute to study of complexes with higher added value. The synthesis of target species can be classified as a ligand exchange reaction between homoleptic BEN complex and lithium precursor. Selected complexes were used as initiators of polymerization reaction (lactide, ε-caprolactone) and for asymmetric Michael addition.	carborane, zinc complexes, enaminone, NMR, X-ray, polymers
