摘要

Ring closing metathesis of the vinyl group-terminated oligoethers catalyzed by RuCl2 (CHPh)(PCy3) 2 yielded macrocyclic polyethers containing vinylene group. The 1H and 13C NMR spectra indicated the presence of CC double bond (trans/cis= ca. 80: 20). The obtained 23-membered cyclic ether reacted with benzyl (anthrylmethl) ammonium hexafluorophosphate to produce the pseudo-rotaxane as colorless crystals. X-ray ...
