Diaryliodonium(III) salts have been established as powerful halogen-bond donors in recent years. Herein, a new structural motif for this compound class was developed: iodoloisoxazolium salts, bearing a cyclic five-membered iodolium core fused with an isoxazole ring. A derivative of this class was synthesized and investigated in the solid state by X-ray crystallography. Finally, the potential as halogen-bonding activator was benchmarked in solution in the gold-catalyzed cyclization of a propargyl amide.
近年来,二芳基碘鎓(III)盐已被确立为强大的卤素键供体。在此,开发了这类化合物的一种新结构 motif:碘代异恶唑鎓盐,其具有与异恶唑环稠合的环状五元碘鎓核心。合成了该类的一种衍生物,并通过X射线晶体学对其固态进行了研究。最后,在炔丙基酰胺的金催化环化反应中,在溶液中对其作为卤素键活化剂的潜力进行了基准测试。
