9-二硫代芳甲酸酯基芴的合成

Synthesis of 9H-fluoren-9-yl aromatic dithiocarboxylates

以9-溴芴和卤代芳烃为原料,首次经由格氏反应合成了5种有望做为可逆加成-断裂链转移试剂的双硫酯类化合物,并用1HNMR、13CNMR、IR、MS和元素分析对所得化合物结构进行了表征。

Five 9H-fluoren-9-yl aromatic dithiocarboxylates（9H-fluoren-9-yl benzodithioate,9H-fluoren-9-yl 4-bromobenzodithioate,9H-fluoren-9-yl 4-methylbenzodithioate,9H-fluoren-9-yl 4-methoxybenzodithioate,9H-fluoren-9-yl naphthalene-1-carbodithioate）,which may be used as the RAFT（reversible addition-fragmentation chain transfer） agent,were synthesized from the starting materials 9-bromofluorene and aryl halide.The structure of the resulting products was characterized by NMR,IR,elementary analysis and UV-Vis absorption spectroscopy.
