Unprecedented H-atom transfer from water to ketyl radicals mediated by Cp(2)TiCl.
The H-atom transfer (HAT) from water to ketyl radicals, mediated by titanocene(iii) aqua-complexes, can explain the Ti(III)-promoted reduction of ketones in aqueous medium better than the conventional House mechanism. Moreover, we also report novel evidences supporting the existence of these titanocene(iii) aqua-complexes.
