Biaryl cross-coupling reactions: convenient routes to new functionalized calix[8]arenes
Abstract
Calix[8]arene substituted by styryl groups was prepared by Suzuki and Negishi type cross-coupling reactions respectively via the fully para brominated- and iodinated-octamethoxycalix[8]arene as intermediates. Single X-ray structure of the octabromo-octamethoxycalix[8]arene has been resolved.
