Photochemical reactions of platinum(II) bis(acetylacetonato) with nitrogen containing Lewis bases

Upon 300 nm irradiation, the reactions of platinum(II) bis(acetylacetonato) with pyridine, piperidine, 2-picoline, 3-picoline and 4-picoline result in two types of stable complexes: Pt(acac)(γ-acac)base and Pt(γ-acac)2base2. These complexes have been characterized by 1H NMR, 13C NMR, IR, GC–MS (DIP), UV–vis absorption spectroscopy and crystal X-ray diffraction studies. The quantum yields of disappearance of Pt(acac)2 and the first-order rate constants have also been measured.
