On August 4, 2020, Behm, Kira; Fazekas, Eszter; Paterson, Martin J.; Vilela, Filipe; McIntosh, Ruaraidh D. published an article.Formula: C14H22O The title of the article was Discrete Ti-O-Ti Complexes: Visible-Light-Activated, Homogeneous Alternative to TiO2 Photosensitisers. And the article contained the following:
A series of novel bimetallic TiIV amine bis(phenolate) complexes was synthesized and fully characterised. X-ray crystallog. studies revealed distorted octahedral geometries around the Ti centers with single or double oxo-bridges connecting the two metals. These robust, air- and moisture-stable complexes were employed as photosensitizers generating singlet oxygen following irradiation with visible light (420 nm) LED module in a com. flow reactor. All five complexes showed high activity in the photo-oxygenation of α-terpinene and achieved complete conversion to ascaridole in four hours at ambient temperature The excellent selectivity of these photosensitizers towards ascaridole (vs. transformation to p-cymene) was demonstrated with control experiments using a traditional TiO2 catalyst. Further comparative studies employing the free pro-ligands as well as a monometallic analog highlighted the importance of the ′TiO2-like′ moiety in the polymetallic catalysts. Computational studies were used to determine the nature of the ligand to metal charge transfer (LMCT) states and singlet-triplet gaps for each complex, the calculated trends in the UV-vis absorption spectra across the series agreed well with the exptl. results. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Formula: C14H22O
