| Summary: | Preparation, characterization, and reactivity of (η<sup>2</sup>- alkyne)(meso-tetratolylpoprphrinato)titanium(II) complexes are described, along with inetermetal oxygen atom transfer reactions involving Ti(IV) and Ti(III) porphyrin complexes. The η<sup>2</sup>- alkyne complexes are prepared by reaction of (TTP)TiCl<sub>2</sub> with LiAlH<sub>4</sub> in presence of alkyne. Structure of (OEP)Ti(η<sup>2</sup>-Ph-C≡C-Ph) (OEP=octaethylporphryin) was determined by XRD. The compounds undergo simple substitution to displace the alkyne and produce doubly substituted complexes. Structure of (TTP)Ti(4-picoline)<sub>2</sub> was also determined by XRD. Reaction of (TTP)Ti=O with (OEP)Ti-Cl yields intermetal O/Cl exchange, which is a one-electron redox process mediated by O atom transfer. Also a zero-electron redox process mediated by atom transfer is observed when (TTP)TiCl<sub>2</sub> is reacted with (OEP)Ti=O. |
