Arranging an aromatic cyclic trimer into a tripodal molecule was achieved by the reaction of tri(bromomethyl)benzene with substituted benzimidazoles. The edge-to-face C–H⋯π interactions in the trimer stabilize the conformation of flexible molecules.
Neutral and heteroleptic metallocalix[4]arenes with covalently attached free functionalized benzimidazolyl units were synthesized using Re2(CO)10, a flexible tritopic N donor and rigid bis-chelating unit, via a one-pot process.
利用 Re2(CO)10(一种灵活的三位 N 供体和刚性双螯合单元),通过一锅法合成了具有共价连接的游离官能化苯并咪唑单元的中性和杂环金属羰基[4]烷。
