Yield:233-74-9 92%
Reaction Conditions:
with indium trifluoromethanesulfonate in chlorobenzene at 132; for 5 h;
Steps:
12 Example 12
Chlorobenzene (40ml) andα-Naphthyl isothiocyanate (3.70g, 20mmol) was added to the reactor equipped with a thermometer and a reflux condenser, and indium trifluoromethanesulfonate (16.86g, 30mmol) was added to the reactor at one time, and the temperature of the reaction system was increased. The boiling point of chlorobenzene was raised to 132°C and refluxed. After the indium trifluoromethanesulfonate was completely dissolved, the reaction was refluxed for 5.0 hours. The filtrate was collected by filtration, and the solvent in the filtrate was evaporated by a rotary evaporator to obtain the crude product. The obtained crude product was recrystallized with ethyl acetate, and the white solid therein was filtered off with suction to obtain 3.40 g of polycarbonate anti-high temperature degradation agent L with a yield of 92%.
