Synthesis of octamethyltetrasila[2.2]paracyclophane: a high yielding Würtz coupling reaction using Cr(CO)3templates
摘要:
Octamethyltetrasila[2.2]paracyclophane and [2.2]paracyclophane are prepared in high yield from the Wurtz coupling reaction of [Cr(CO)(3){eta(6)-C6H4(SiMe(2)Cl)(2)-1,4}] and [Cr(Co)(3){eta(6)-C6H4(CH2Br)(2)-1,4}], respectively.

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.
