烯醇硅醚对[60]富勒烯的亲核加成反应

Nucleophilic Addition of Silyl Enol Ethers to [ 60]Fullerene

在空气气氛和非极性溶剂(甲苯)中1-(4＇-甲氧基苯基)-1-三甲基硅氧基乙烯与[60]富勒烯反应得到了非预计的环丙基骈[60]富勒烯衍生物(5).在无氧和极性非质子性溶剂(THF)中进行上述反应,得到了1,2-取代[60]富勒烯亲核加成产物(3).对反应的机理作了合理的阐述.

1 - (4 - Methoxyphenyl) - 1 - (trimethylsilyloxy) ethylene was reacted with [60] fullerene in air atmosphere and nonpolar solvent (toluene) to form an unpredicted product of cyclopropano [60] fullerene derivative (5). In the presence of polar aprotic solvent, tetrahydrofuran, and under non - oxygen condition, the normal nucleophilic addition product 1, 2 - substituted [60] fullerene (3) was obtained. A reasonable mechanism has been suggested.
