The present invention refers to a process making use of a radical aromatic substitution reaction for preparing an Ar-N-R1-N-diazoniabicyclo[2.2.2]octane dianion salt, wherein an aromatic hydrocarbon Ar is bonded to a 1-R-1,4-diazabicyclo[2.2.2]octane2+] 2X- compound, X being an anion.
                            本发明涉及一种利用自由基芳香取代反应制备 Ar-N-R1-N-diazoniabicyclo[2.2.2]octane 二元阴离子盐的工艺,其中
芳香烃 Ar 与 1-R-1,4-二氮杂
双环[2.2.2]辛烷2+] 2X- 化合物键合,X 为阴离子。
