Novel N-fluorotriazinium electrophilic fluorinating agents have the Formula I:
1
wherein three A moieties are independently CR, where each R is, independently, hydrogen, halogen, hydroxyl, (primary, secondary or tertiary) amino, amino, cyano, perfluorothio, hydroxysulfonyl, halosulfonyl, hydrocarbyloxysulfonyl, or a carbon-containing substituent selected from the group consisting of optionally substituted hydrocarbyl, hydrocarbyloxy, hydrocarbyloxycarbonyl, and hydrocarbylthio groups, and at least one R is neither hydrogen nor halogen; two A moieties are independently Z, where each Z is independently nitrogen or a quaternary nitrogen atom and Y is a counterion or group of counterions which are inert to chemical attack by fluorine, or adjacent triazinium moieties are linked by a common R substituent to provide an oligomer or polymer. Preferably the compounds are 1,3,5-triazinium compound in which all R are the same, optionally perfluorinated, alkyl or alkoxy groups; Z
1
and Z
2
are both nitrogen and Y
−
is triflate. Compounds of Formula I are especially useful in fluorinating carbanionic species or activated aromatic compounds.
新型N-氟三唑基电泳氟化试剂具有I式:1其中三个A基团独立地为CR,其中每个R独立地为氢、卤素、羟基、(一级、二级或三级)氨基、氨基、氰基、全氟硫基、羟基磺酰基、卤代磺酰基、烃氧基磺酰基或从可选取的含碳取代基团组中选择的含碳取代基团,该组包括可选取的取代的烃基、烃氧基、烃氧羰基和烃硫基基团,并且至少有一个R既不是氢也不是卤素;两个A基团独立地为Z,其中每个Z独立地为氮或季铵氮原子,Y为对氟化学攻击惰性的反离子或反离子组,并且相邻的三唑基团通过共同的R取代基连接以提供寡聚体或聚合物。优选地,化合物是所有R都相同的1,3,5-三唑基化合物,可选地是全氟化的烷基或烷氧基基团;Z1和Z2均为氮,Y-为三氟甲磺酸盐。I式化合物在氟化碳负离子物种或活性芳香化合物方面特别有用。
