REACTION OF [60]FULLERENE WITH EPOXIDES UNDER PHOTO-IRRADIATION: SYNTHESIS OF C_(60)-FUSED TETRAHYDROFURAN DERIVATIVES

摘要

The photoreactions of [60]fullerene (C_(60)) with various epoxides have been investigated. Trans 2-aroy1-3-aryloxiranes reacted with [60]fullerene giving both the major cis products and the minor trans adducts. The influence of substituent group on aryl ring on the photoreaction is entirely different from that of preliminary reported thermal reaction. In addition, the photo condition could avoid the decomposition of some original epoxides compared to the thermal condition at high temperature. It provides a simple and efficient route to synthesize C_(60)-fused tetrahydrofuran derivatives.
