Preparation of some cyclopentadienyl titanium complexes and crystal structure of ( η5-pentamethylcyclopentadienyl) {(1 R,2 S,3 R)- exo-3[( R)-2-phenyl-2-olato-ethyl}] sulphenyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-olato chlorotitanium(IV): [Cp ∗Ti(OC 18H 24SO)Cl]·C 6H 6

Abstract

The reaction of (1 R,2 S,3 R)- exo-3[( R)-2-phenyl-2-hydroxyethyl]sulphenyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol ( 1) with Cp ∗TiCl 3 in the presence of Et 3N furnishes the product Cp ∗Ti(OC 18H 24SO)Cl in high yield {Cp ∗ = pentamethylcyclopentadienyl; OC 18} H 24SO = (1 R,2 S,3 R)- exo-3[(R)-2- phenyl-2-olato-ethyl]sulphyl-1,7,7-trimethylbicyclo [2.2.1]heptan-2-olato. The structure of Cp ∗Ti(OC 18H 24SO)Cl·C 6H 6 ( 2) has been determined by X-ray crystallography. The reaction of Cp 2Ti(X)Cl (X = Me, Cl) with 2-methoxybenzyl alcohol in the presence of Et 3N under refluxing benzene gave the product Cp 2Ti(X)( o-OCH 2C 6H 4OMe) (X = Cl, Me).
