چکیده
The reaction of the 17e nickel(I) radical [CpNi(IDipp)] (1, IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with P4 results in a nickel tetraphosphide [{CpNi(IDipp)}2(μ-η(1):η(1)-P4)] with a butterfly-P4(2-) ligand; related chalcogenides [{CpNi(IDipp)}2(μ-E2)] (E = S, Se, Te) and [{CpNi(IDipp)}2(μ-E3)] (E = S, Se) are formed with S8, Se∞ and Te∞.

متن کاملDinuclear Nickel(I) and Palladium(I) Complexes for Highly Active Transformations of Organic Compounds.
In typical catalytic organic transformations, transition metals in catalytically active complexes are present in their most stable valence states, such as palladium(0) and (II). However, some dimeric monovalent metal complexes can be stabilized by auxiliary ligands to form diamagnetic compounds with metal-metal bonding interactions. These diamagnetic compounds can act as catalysts while retaini...

Titanocene(III)-mediated radical processes are important tools for the formation of C C bonds under mild conditions, and are compatible with many functional groups. Moreover, titanium(III) complexes can be used substoichiometrically, which has allowed the development of enantioselective versions of these reactions. A serious limitation of these radical processes, however, derives from the fact ...
