Abstract
Polymer-supported triphenylphosphine oxide chlorides and nitrates of N i, Zn and Cd have been synthesised and characterised. The study of the ir reactivity with SO2 in the solid state and in toluene slurries at r oom temperature has been performed. The SO2 absorption of these metal precursors was also monitored by thermogravimetric analyses. On exposu re 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 an d nitrate ions appear to be replaced by sulfate.
