organometallic reagents and frequently used in difficult metallation reactions. However, their direct use in the formation of C−C bonds is less established. Although remarkable advances in the coupling of aryllithium compounds have been achieved, Csp2−Csp3 coupling reactions are very limited. Herein, we report the first general protocol for the coupling or aryl chlorides with alkyllithiumreagents. Palladium

conjugate addition of pyrroles to β-Fluoro-β-nitrostyrenes was investigated. The reaction was found to proceed under solvent-free conditions to form 2-(2-Fluoro-2-nitro-1-arylethyl)-1H-pyrroles. The effectiveness of this approach was demonstrated through the preparation of a series of the target products in a quantitative yield. The kinetics of a conjugate addition of pyrrole was studied in detail

This invention relates to compounds represented by formula:
wherein M is a group 3, 4, 5 or 6 transition, lanthanide, or actinide metal atom; E is an indenyl ligand substituted in any position with at least one aromatic or pseudoaromatic heterocyclic substituent that is bonded to the indenyl ring through a nitrogen or phosphorous ring heteroatom; A is a substituted or unsubstituted cyclopentadienyl, heterocyclopentadienyl, indenyl, heteroindenyl, fluorenyl, or heterofluorenyl ligand, or other mono-anionic ligand, or A may, independently, be E; Y is an optional bridging group; y is zero or one; X are, independently, univalent anionic ligands, and provided that when A is E, and y is one, and Y is bonded to the one position of each indenyl ligand, and per indenyl ligand there is only one aromatic heterocyclic or pseudoaromatic heterocyclic that is bonded to the indenyl ligand.
