Trihalide-included (I2, Br2 and IBrCl−) bambus[6]urils in halogenation and iodine-catalysed reactions

Abstract

We have prepared two new heterotrihalides inside methyl-bambus[6]uril, [Br2Cl]−@MeBU[6] and [BrICl]−@MeBU[6], both in solution and in the solid state. These heterotrihalides were used alongside with the first one our group has produced, [I2Cl]−@MeBU[6], as halogenation agents in classical halogenation and iodine-based catalysts for organic reactions, with comparable yields to those obtained with pure dihalogens.
