Abstract
Abstract Polymer-supported triphenylphosphine oxide chlorides and nitrates of Ni, Zn and Cd have been synthesised and characterised. The study of their reactivity with SO2 in the solid state and in toluene slurries at room temperature has been performed. The SO2 absorption of these metal precursors was also monitored by thermogravimetric analyses. On exposure to sulfur dioxide, some SO2-adducts of stoichiometric formula could be isolated and characterised by infrared spectroscopy and desorption studies. Nitrate complexes show an additional interaction with SO2 and nitrate ions appear to be replaced by sulfate. Dedicated to the Royal University of Santiago the Compostela in the Year of its 500th Anniversary.
