The design and synthesis, as well as solid state and ESR characterisation of three new triradicals based on phenyl ethynyl backbone bearing nitronyl-nitroxide and imino-nitroxide groups, are reported. The synthesis of these compounds was based on palladium-coupling reactions between alkynyl and bromo derivatives. An ESR study showed magnetic interactions between the radicals through the phenyl ethynyl-coupling
报道了基于带有乙氧基-亚硝基氧化物和亚氨基-亚硝基氧化物基团的苯基乙炔基骨架的三种新的三基自由基的设计,合成以及固态和ESR表征。这些化合物的合成是基于炔基和溴衍生物之间的钯偶联反应。一项ESR研究表明,自由基之间通过溶液中的乙炔基偶联单元发生了磁性相互作用。
