Selective synthesis of conformationally restricted mono-cyclopentadienyl titanium(iv) complexes of p-tBu-calix[6]arene

Abstract

Reaction of p-^tBu-calix[6]arene with potassium metal in methanol followed by [TiCp₂Cl₂] affords novel mononuclear and binuclear monocyclopentadienyl titanium(IV) complexes, both having the same inverted double cone conformation with a Cp in one of the cavities, in both complexes.
