The copper compound [Cu(C6Cl2F3)(tht)]4 (1) (tht: tetrahydrothiophene)
is an excellent catalyst for the trans- to cis- isomerization of
complexes [PdAr2(tht)2](Ar: fluoroaryl) and also for the exchange of aryls
between those palladium complexes. Herein, we also communicate the synthesis
and characterization of 1, and some of its derivatives. The x-ray structure
of 1 shows a linear chain of copper atoms, supported by fluoroaryl rings.
The NMR 19F-DOSY study indicates that this structure is preserved in solution
although in equilibrium with other species.
