For some time we have been interested in the reaction kinetics of sulfur addition to trivalent organophosphorus compounds and have used IR spectroscopy to follow the progress of these reactions. Many spectral changes occur upon sulfur addition which are not specifically related to the addition of sulfur, but rather to a change in valence of phosphorus from three to five. These changes involve shifts of C-H stretches and skeletal vibrations to higher frequencies. Similar changes occur upon the… CONTINUE READING
