Unusual Formation Reaction of 2'-(Methyl)-3'-acetyl-1,9- dihydro(4',5'-dihydrofurano) [60]fullerene in reaction of C_(60) with Complexes VO(acac)2 and Mo02(acac)2

摘要

A preparation method was developed for 2'-(methyl)-3'-acetyl-l,9-dihydro(4',5'- dihydrofurano) [60]fullerene based on the liquid phase oxidation of C_(60) using VO(acac)2 and MoO2(acac)2. Derivatives of fullerene C_(60) containing heteroatoms are promising for simulation of photosensibilization and photosynthesis processes important for investigation of biological systems [1]. In particular, compared with the initial C_(60) its carbonyl derivatives containing reactive functional groups (C=O and C=C) possess significantly larger synthetic potential for the preparation of new materials and biologically active compounds [2-4]. One of the most promising routes to the fusion to C_(60) molecule of five-membered heterocycles containing a carbonyl group is the [2+3]-cycloaddition of P-diketonates and |3-ketoesters with the formation of the corresponding dihydrofuran derivatives [5-9].
