Herein, we demonstrate the synthesis of azafluoranthene derivatives under mild conditions via [2+2+2] cycloaddition of 1,6-diynes and nitriles catalyzed by CoBr2/dppp, exhibiting good atom economy. This procedure uses an inexpensive ligand and an earth-abundant metal as catalyst to lower the cost of synthesis. Several azafluoranthenes are produced in 28–95% yields using this approach, featuring mild
在此,我们证明了在CoBr 2 /dppp催化下,通过1,6-二炔和腈的[2+2+2]环加成在温和条件下合成氮杂荧蒽衍生物,表现出良好的原子经济性。该过程使用廉价的配体和地球丰富的金属作为催化剂,以降低合成成本。采用该方法可生产多种氮杂荧蒽,收率达28%~95%,具有条件温和、底物范围广、官能团耐受性好的特点。一些氮杂荧蒽的荧光光谱表明这些支架对于材料科学具有良好的光物理性质。
