摘 要:親核加成是Fullerene[60]典型、特征的反應,由于富勒烯分子有很多反應活性點(diǎn),大多數親核取代發(fā)生多元加成,生成難分離的混合物。Fullerene[60]和氰化鈉的加成反應證明:以N,N-二甲基甲酰胺和鄰二氯苯為混合溶劑,氰基負離子(CN-)與C60能發(fā)生可控的一元親核加成反應,生成[C60(CN)]-,不分離此中間體,直接加入三氟乙酸得到產(chǎn)物C60(CN)H;如果在C60(CN)-的溶液中加入對甲苯磺酰氰,可高收率地得到C60(CN)2。利用1H NMR、質(zhì)譜、元素分析對產(chǎn)物的組成和結構進(jìn)行了確認和鑒定。 |

Abstract:Nucleophilic addition is a characteristic reaction of a buckminsterfullerene. However,the addition of nucleophiles to C60,in most cases leads to a myriad of different polyadducts which are difficult to separate into isomerically pure compounds. The addition of NaCN to C60 revealed that the controllable mono-adduction of CN to C60 was obtained,which produced only C60(CN)-,using the mixture of DMF and 1,2-dichlorobenzene (ODCB) as the solvent. Without separation,protonation of C60(CN)- with trifluoroacetic acid produced C60(CN)H as the single isomer. When C60(CN)- was treated with tosyl cyanide at room temperature,the C60(CN)2 was formed,as a single isomer,in high yield. The products were characterized by 1H NMR,ESI-MS and elemental analysis. |
