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.
