Reaction Steps

9-Fluorenone (6.44 g, 0.0358 mol, 1.00 equiv.), molten phenol (70.0 g, 0.744 mol, 20.8 equiv.), and deionized water (1.93 g, 0.107 mol, 3.00 equiv.) is added to the reactor (reactor design 3). The reaction mixture is heated to 45° C. with stirring under a pad of nitrogen. 3-Mercaptopropanesulfonic acid (0.385 g, 2.47 mmol, 0.0690 equiv.) is added slowly over approximately 1 minute to the reaction mixture at 45° C. The reaction is monitored throughout the reaction period by collecting samples and analyzing by HPLC. The 9-fluorenone is found to be 4% consumed within 9 minutes, 13% consumed within 1 hour, 29% consumed within 3.5 hours, and 94% consumed within 20.5 hours. HPLC analysis (analytical method 3) gives the following relative area % analysis for the reaction products (fluorenone area not included) at 94% conversion:
