Synthesis of rhodium complexes derivedfrom benzimidazolin-2-ylidene ligands andfirst used for the addition of arylboron tobenzonitriles

Benzimidazolium salts and their new rho-dium complexes ([Rh(COD)(NHC)Cl]) weresynthesized and characterized. The additionof sodium tetraphenylborate to nitriles inthe presence of a catalytic amount of a rho-dium NHC complexes was examined. Cor-responding carbonyl compounds wereobtained in good yields.

Synthesis of novel palladium allyl complexesbearing heteroditopic NHCeS ligands. Ki-netic study on the carbene exchange be-tween bis-carbene palladium allyl complexes

Novel palladium allyl complexes withNHCeS ligands were synthesized. Prepara-tion of mixed bis-carbene complexes bear-ing two different carbenes simultaneouslycoordinated to the palladium center yieldthe formation of an equilibrium mixture ofthe two homoleptic and the mixed bis-carbene species. The reaction rates weremeasured and a mechanistic hypothesisadvanced.

Two substrates, three products: Reactionsbetween ferrocene-carboxaldehyde anddioxaphospholene, characterization andcrystal structures of oxygenated C3- andC4-chain-containing ferrocenes

Depending on the experimental conditionsused, the reaction between biacetyl trime-thylphosphite adduct and ferrocenecarbox-aldehyde gives rise to either 1-ferrocenyl-1,2-propanedione, or 4-methoxy-4-ferrocenyl-3-hydroxy-3-methyl-2-butanone (illustrated)as a single diastereoisomer, or 1-(3-oxo-2-methylbut-1-enyl)ferrocene; this behaviorcould originate from a common charge sep-arated state with a carbonium ion stabilizedby the ferrocene unit.

Syntheses and properties of cyclosilazanesand cyclocarbosilazanes

The review evaluates known syntheticmethods of cyclo(carbo)silazanes and sum-marises important physico-chemical prop-erties. It is compiled as a guide for thetargeted preparation of various classes ofrespective compounds. The review also in-cludes useful transformations of N-unsub-stituted cyclic derivatives and data onhydrolytic stability of cyclo(carbo)silazanes.

Synthesis and structural diversity of lan-thanide amidate complexes and their cata-lytic activities for the ring-openingpolymerization of rac-lactide

Both anionic and neutral lanthanide com-plexes stabilized by amidate ligand can beprepared through protonolysis reactions. Inthe neutral lanthanide amidate complexes,an unprecedented NeHeN bond betweentwo of the amidate ligands is formed, mak-ing it the most notable difference fromnormal neutral analogs.
