(a) Comparative reactivity analysis of similar organotitanium systems, including hydroxyl radical formation by a substituted ansa-titanocene dihydroxido complex under daylight irradiation and the established ability of titanium oxo (Ti=O) groups to convert to peroxo species (Ti-O-O-) upon H₂O₂ exposure; (b) Observations of ordered reaction sequences across multiple sub-cycles of the photosynthetic cascade, as illustrated in Figures and (c) Expected formation of trichloro-and dichloro-titanium PI complexes upon daylight-induced reduction of the titanium tetrachloride PI coordination compound .
