The cross-coupling reactions of 4-bromo[2.2]paracyclophane withp-tolylmagnesium bromide in the presence of various palladium and nickel complexes have been studied. It was found that [1,1 ′-bis(diphenylphosphinoferrocene)]palladium dichloride (PdCl2 · dppf) shows the highest catalitic activity in this reaction. A series of new mono- and diaryl [2.2]paracyclophane derivatives with various substituents

substituent to form (in low yields) the corresponding mononuclear complex or binuclear complexes with both the aromatic ring of paracyclophane and the aryl ring of the substituent involved in coordination. The structure of such complex, namely, [4-(η6-2,4,6-trimethylpheny)-11-16-η6-[2,2]paracyclophane]bis[tricarbonylchromium(0)] was confirmed by X-ray diffraction study.
