Abstract
From the dilithio reagent o-C6H4((NLiSiPr3)-Pr-i)(2) (2), the new comp lexes [o-C6H4((NSiPr3)-Pr-i)(2)]Zr-2 (3), [o-C6H4(Nsi(i)Pr(3))(2)]Zr(O (t)Bu)(2) (4), [o-C6H((NSiPr3)-Pr-i)(2)]TiCl2 (5), and [o-C6H4((NSiPr3 )-Pr-i)(2)]TiMe(2) (6) have been prepared. X-ray crystallographic and variable-temperature NMR studies characterize these complexes as posse ssing eta(4)-C6H4((NSiPr3)-Pr-i)(2) ligands (bonded to the metal via t wo carbon atoms in the phenylene group), which undergo a eta(4)-eta(2) fluxional process in solution.
