Outline of Final Research Achievements |
A unique strategy for benzylation and C-H activation by the (η3-benzyl)palladium(II) system from a water-soluble palladium(0)/sodium diphenylphosphinobenzene-3-sulfonate (TPPMS) catalyst and benzyl alcohol in water is developed. Notably, water may activate the sp3 C-O bond, then stabilize the Pd(II) cation species by hydration, which can then undergo innovative direct transformation reactions. N-Benzylation/benzylic C-H activation cascade is devised as a novel and efficient synthetic route for N-(1,2-diphenylethyl)anilines or 3-phenyl-3,4-dihydro-(2H)-1,2,4-benzothiadiazine-1,1-dioxides. A direct catalytic substitution of benzylic alcohols, which affords the desired products along with water as the sole co-product, is an efficient and environmentally benign method.
