Cp2TiCl2 (Cp = η⁵-C5H5; H2Pc = phthalocyanine) reacts with 1.9 equivalents of PhSCH2Li to give Cp2Ti(CH2SPh)2 (I), the structure of which follows from the results of elemental analysis, 1H NMR and mass spectroscopic investigations and proptolysis to form PhSCH3.I decomposes in toluene at 100 degC, with the methylene group being liberated to form 2 (II) (ca. 31percent) and Cp2Ti(SPh)2 (III) (ca. 16percent).Na*4THF (IV) (μ_eff. 0.12 BM) has been obtained as green-black, air-sensitive crystals in an oxidative addition reaction from PhSCH2Cl and iron(0) phthalocyanine.In boiling THF the organyl group is gradually split off without formation of a considerable amount of the corresponding thiophenolato complex.The results are in agreement with the assumption that the formation of an η²-thioanisolyl structure as an unstable intermediate is essentially important for the conversion of the thioanisolyl into the thiophenolato complexes.
