We report synthesis and structural characterization of bis-cyclooctatetraene trinuclear palladium sandwich complexes. The non-planar cyclooctatetraene ligands flank an isosceles Pd3 triangle, which is supported by one equatorial ligand.

Stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar X groups; X =OH, SH, H, F, CN, and NO). There are meaningful correlations between changes of geometricalparameters and t...

Abstract— We report two new analogs of the N871b fluorogen that contain CycloOctaTetraene. have studied photostability fluorescent complexes FAST protein with compounds by confocal microscopy when staining living HeLa Kyoto cells. One exhibits a higher in complex than previously published fluorogen. The results indicate cyclooctatetraene is highly promising compound for modification dyes based ...

tetrachloride in T H F produces blue-green crystals that are stable to water and to aqueous acid or alkali. The compound can be sublimed or recrystallized from benzene or toluene. The compound is pyrophoric but controlled air oxidation yields uranium oxides and cyclooctatetraene. Mass spectral analysis gives a parent peak for U(CeH& and the fragmentation pattern indicates a ferrocene-like sandw...

Transformation of the simple hydrocarbon cyclooctatetraene into a variety of polycyclic skeletons was achieved by sequential coordination to iron, reaction with electrophiles followed by allylated nucleophiles, decomplexation and olefin metathesis.
