Multilayered iron complexes of [2.2]paracyclophane.

چکیده
Recent syntheses of ruthenium complexes of [2.2]paracyclophane provided a highly interesting class of compounds, the multilayered transition metal complexes of cyclophanes. The present study discloses that arene-metal exchange procedures with ferrocene derivatives, effected either photochemically or by Lewis acid catalysis, are convenient methods for preparing the analogous multilayered iron complexes of [2.2]paracyclophane.

Trinuclear palladium addition to unsaturated carbocycles.
The trinuclear palladium addition to monocyclic unsaturated hydrocarbons was revealed. The trinuclear adduct of [2.2]paracyclophane, cycloheptatriene (CHT), or cyclooctatetraene (COT) was obtained by treatment of the corresponding tripalladium sandwich complexes with 3 equiv. of 1,10-phenanthroline. In the trinuclear adduct of [2.2]paracyclophane or CHT, a Pd2 unit and a Pd1 unit synfacially co...
متن کاملEnantiospecific synthesis of [2.2]paracyclophane-4-thiol and derivatives
This paper describes a simple route to enantiomerically enriched [2.2]paracyclophane-4-thiol via the stereospecific introduction of a chiral sulfoxide to the [2.2]paracyclophane skeleton. The first synthesis of an enantiomerically enriched planar chiral benzothiazole is also reported.
متن کامل[2.2]Paracyclophane derivatives containing tetrathiafulvalene moieties
The synthesis of [2.2]paracyclophane derivatives containing tetrathiafulvalene units has been accomplished by the coupling reaction of 4-([2.2]paracyclophan-4-yl)-1,3-dithiol-2-thione in the presence of trimethylphosphite. The 1,3-dithiol-2-thione derivative was in turn synthesized by the regioselective bromination of 4-acetyl[2.2]paracyclophane, then through the corresponding dithiocarbamates ...
متن کاملPlanar chiral [2.2]paracyclophane-based bis(thiourea) catalyst: application to asymmetric Henry reaction.
A bis(thiourea) organocatalyst with a planar chiral [2.2]paracyclophane backbone has been synthesized and applied to the Henry reaction. The obtained high reactivity and enantioselectivity from the reaction of aromatic aldehydes with nitroalkanes suggested the significant potential of [2.2]paracyclophane to serve as the backbone of the organocatalyst.
متن کاملTwo-photon absorption in three-dimensional chromophores based on [2.2]-paracyclophane.
A series of alpha,omega-bis donor substituted oligophenylenevinylene dimers held together by the [2.2]paracyclophane core were synthesized to probe how the number of repeat units and through-space delocalization influence two-photon absorption cross sections. Specifically, the paracyclophane molecules are tetra(4,7,12,15)-(4'-dihexylaminostyryl)[2.2]paracyclophane (3R(D)), tetra(4,7,12,15)-(4' ...
