实验步骤: 9-Fluorenone (3.65 g, 0.0200 mol, 1.00 equiv.), molten phenol (39.6 g, 0.420 mol, 20.8 equiv.), deionized water (1.09 g, 60.7 mmol, 3.00 equiv.) and diphenylmethane (32.83 g) is added to the reactor (reactor design 2). The reaction mixture is heated to 53° C. with stirring under a pad of nitrogen. 3-Mercaptopropanesulfonic acid (0.158 g, 1.00 mmol, 0.0500 equiv.) is added slowly over approximately 1 minute to the reaction mixture at 53° C. The reaction is monitored throughout the reaction period by collecting samples and analyzing by HPLC. The 9-fluorenone is found to be 11% consumed within 2 hours, 20% consumed within 4.5 hours, and 23% consumed within 6 hours. HPLC analysis (analytical method 3) gives the following relative area % analysis for the reaction products (fluorenone area not included) at 23% conversion: The reaction is monitored throughout the reaction period by collecting samples consumed within 2 hours 20% consumed within 4.5 hours 23% consumed within 6 hours

实验步骤: 9-Fluorenone (3.65 g, 0.020 mol, 1.0 equiv.), molten phenol (39.6 g, 0.420 mol, 20.8 equiv.), deionized water (0.362 g, 20.1 mmol, 0.994 equiv.) and diphenylmethane (32.83 g) is added to the reactor (reactor design 2). The reaction mixture is heated to 53° C. with stirring under a pad of nitrogen. 3-Mercaptopropanesulfonic acid (0.158 g, 1.00 mmol, 0.0500 equiv.) is added slowly over approximately 1 minute to the reaction mixture at 53° C. The reaction is monitored throughout the reaction period by collecting samples and analyzing by HPLC. The 9-fluorenone is found to be 25% consumed within 2 hours, 45% consumed within 4.5 hours, and 57% consumed within 6 hours. HPLC analysis (analytical method 3) gives the following relative area % analysis for the reaction products (fluorenone area not included) at 57% conversion: The reaction is monitored throughout the reaction period by collecting samples consumed within 2 hours 45% consumed within 4.5 hours 57% consumed within 6 hours

实验步骤: 9-Fluorenone (3.65 g, 0.0200 mol, 1.00 equiv.), molten phenol (39.6 g, 0.420 mol, 20.8 equiv.), deionized water (0.055 g, 3.06 mmol, 0.151 equiv.) and diphenylmethane (32.83 g) is added to the reactor (reactor design 2). The reaction mixture is heated to 53° C. with stirring under a pad of nitrogen. 3-Mercaptopropanesulfonic acid (0.170 g, 1.10 mmol, 0.0537 equiv.) is added slowly over approximately 1 minute to the reaction mixture at 53° C. The reaction is monitored throughout the reaction period by collecting samples and analyzing by HPLC. The 9-fluorenone is found to be 49% consumed within 2 hours and 77% consumed within 4.5 hours. HPLC analysis (analytical method 3) gives the following relative area % analysis for the reaction products (fluorenone area not included) at 77% conversion: The reaction is monitored throughout the reaction period by collecting samples consumed within 2 hours 77% consumed within 4.5 hours
