| Abstract: | Cationic complexes (diene)Co(??-C6Me6)]+ (diene is buta-1,3-diene (2a), 5-isopropyl-2-methylcyclohexa-1,3-diene (2b), cycloocta-1,3-diene (2c), and cyclohexa-1,5-diene (2d)) were synthesized by the reaction of Co(??-C6Me6)2]+ (1) with dienes in a CH2Cl2-Me2CO mixture. In the absence of dienes, cation 1 undergoes hydrogenation to form (1,2,3,4,5,6-HMCD-1,3)-Co(??-C6Me6)]+ (HMCD is hexamethylcyclohexadiene, 2e). Structures 2c?Ce]PF6 were determined by X-ray diffraction analysis. According to the DFT calculations, the Co-C6H6 bond in the complexes with conjugated dienes is stronger than that in the complexes with nonconjugated dienes. |
