（E，E，E）- 1,6,11-三（芳烃磺酰基）-1,6,11-三氮杂环五烯-3,8,11-三烯，1由芳烃磺酰胺和反式-1,4-二溴-2-丁烯制备而成。大环1配位钯(0)、铂(0)和银(I)以及钯配合物是铃木交偶联、丁二烯端粒化、炔的氢化芳基化和Heck反应中有用的和可重复利用的催化剂或预催化剂。结构上相关的大环也可以通过类似的合成方法得到。
(E,E,E)- 1,6,11-Tris(arenesulfonyl)-1,6,11-triazacyclopentadeca-3,8,11-trienes, 1, are prepared from arenesulfonamides and trans-1,4-dibromo-2-butene. Macrocycles 1 coordinate palladium(0), platinum(0), and silver(I), and the palladium complexes are useful and reutilizable catalysts or precatalysts in Suzuki cross-couplings, butadiene telomerizations, hydroarylation of alkynes, and in the Heck reaction. Structurally related macrocycles are also available by similar synthetic procedures.
