Formation of inclusion organoactinide complexes with boron-containing macrocycles

J Am Chem Soc. 2004 Apr 28;126(16):5066-7. doi: 10.1021/ja0498843.

Abstract

Reaction of the organoactinide complexes (C5Me5)2AnMe2 (An = Th, U) with catecholborane yields an inclusion complex where the actinide is encapsulated inside a 15-membered, hexaoxo, trianionic macrocycle built from alternating catechol and catecholborate fragments. In the presence of LiOH, a dimer of two encapsulated actinide macrocycles is formed. The X-ray molecular structure for all the complexes is presented.
