✦ Synopsis

Titanium Dioxide Mediated Photocatalytic Conversion of Arenealdehyde Phthalazinylhydrazones to s-Triazolo[3,4-a]phthalazines. -The oxidative intramolecular cyclization of hydrazones (I) to triazolophthalazines (II) represents the first photocatalytic example of an intramolecular cyclization mediated by TiO 2 . -(
