Abstract
Addition of tertiary phosphines (PR3) to [Pt(acac)2] (acac=acetylacetonato-O,O′) causes the rearrangement of one of the O-bonded chelate acac ligands to a C-bonded form giving [Pt(acac)(γ-acac)PR3] (γ-acac=acetylacetonato-C3) (PR3=PPh3, 1a, and P(C6H11)3, 2a). Complexes 1a and 2a were isolated and characterized by means of elemental analysis, infrared and 1H- and 13C-NMR spectroscopy. Some reactions involving complex 1 were investigated. The mechanism of formation of a diethylplatinum complex in the reaction of [Pt(acac)2] with Al(OEt)Et2 and PPh3 is discussed taking into account the rearrangement of the acac ligand from the O-bonded chelate to a C-bonded form.This publication has 18 references indexed in Scilit:
