Chiral Conjoined Cavitands

Irwin, Jacob; Sinclair, David; Edwards, Alison; Sherburn, Michael

Description

Tetrabromocavitand bowls are converted into rim-connected hexabromodimers in one step in 17-22% yields by oxidative coupling of higher order arylcuprates.1H NMR and single crystal X-ray analyses of the rim-connected dimers reveal a conformationally restricted structure in which the rims of the two cavitand bowls describe planes angled at 78.8° to one another. Each of the two bowl cavities are occupied by a guest, in addition to being partially occluded by a portion of the complementary bowl...[Show more]
