摘要：

Triarmed cyclophanes 1 and 2 have been synthesized by i-Bu3Al/TiCl4-catalyzed cyclotrimerization of t-BuSi(OCH2CH2CH2C = CH)3 and characterized by single-crystal X-ray, H-1 and C-13 NMR, and elemental analysis. Macrocyclic cage 1 has a distorted benzene ring, while that of 2 is nearly planar. In 1 and 2 the silicon atom is 3.50 and 3.58 angstrom above the mean plane of the benzene ring. Additional cyclotrimerization studies of this catalyst system are reported.
