In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Application In Synthesis of 1,1′-Ferrocenedicarboxaldehyde. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde
Paramagnetic and semiconducting 1:1 salts of 1,1?-disubstituted ferrocenes and [Ni(mnt)2]-. Synthesis, structure, and physical properties
The ferrocene-based electron donors 1,1?-bis[2-(4-(methylthio)phenyl)-CE)-ethenyl]ferrocene (2), 1,1?-bis[2-(4-methoxyphenyl)-CE)-ethenyl]ferrocene (3), 1,1?-bis[(1,3-dithiolo[4,5-b][1,3]-dithiol-2-ylidene)methyl]ferrocene (4), and 1,1?-bis[(1,3-benzodithiol-2-ylidene)methyl]ferrocene (5) were found to react with ferrocenium bis(maleonitriledithiolato)nickelate (1-) ([FeCp2]+[Ni(mnt)2]-, 6) to afford the corresponding 1:1 paramagnetic salts 7-10, containing 1,1?-disubstituted ferrocenium derivatives. SQUID magnetic susceptibility measurements of these new compounds showed a behavior dominated by antiferromagnetic interactions within pairs of [Ni(mnt)2]- ions. Pressed pellets of compounds 7 ([2][Ni(mnt)2]) and 9 ([4]-[Ni(mnt)2]) are semiconducting, with a relatively large conductivity activation energy (0.85 and 1.13 eV). Crystals of 7 reveal the monodimensional nature of the compound. Each separate stack of [Ni(mnt)2]- ions is flanked by two ferrocenium stacks. Ni-Ni distances alternate between 3.67 and 3.99 A.
