Calix[4]arene Derivatives of Titanium and Zirconium Alkoxides

摘要

Reaction of Ti(OBu)(4) or Zr(OBu)(4) with tbutyl-calix[4]arene, calixd(tBu)(OH)(4), led to the formation of Ti-2(OBu)(2)[calix(tBu)O(3)(OH)](2) and Zr-3(OBu)(8)(calixd(tBu)O(4)), respectively. Upon in situ generation of water in the reaction with Zr(OBu)(4), the partially hydrolyzed compound Zr4O(OBu)(6)(calixtBuO(4))(2) (BuOH)(2) was isolated.
