posted on 2006-05-26, 00:00 authored by Guan-Wu Wang, Hai-Tao Yang, Ping Wu, Chun-Bao Miao, Yu XuThe thermal reaction of [60]fullerene (C60) with the carbonyl
ylides generated in situ from trans-epoxides to give C60-fused tetrahydrofuran derivatives has been investigated. The
reaction of C60 with trans-2-benzoyl-3-aryloxiranes afforded
only cis-products, while the reaction of C60 with 2-cyano-2-ethoxycarbonyl-3-aryloxiranes gave exclusively or predominantly cis isomers. The isomeric distributions of the
latter reactions were drastically affected by the substituent
on the phenyl ring.
