| Popis: | Dissymmetrical vanadocenes CpCp′V are prepared by reduction of the corresponding dichlorides CnCp′VCl2 (Cp = C5H5 ; (Cp′ = C5H4R). Like vanadocene they display a carbenoď behavior and can be coordinated to CS2 and acetylenic compounds. The addition of dissymmetrical acetylenes involve the formation of a chiral center at vanadium. This chirality is detected by partial chromatographic separation of diastereoisomers CpCp″V* (RCCR*) which bear a second chiral center on acetylenic ligand. |
