Yield:95-16-9 97%
Reaction Conditions:
with indium(III) trichloride in acetonitrile at 80; for 4 h;
Steps:
1 Example 1
Acetonitrile (40 ml) and phenyl isothiocyanate (2.70 g, 20 mmol) were successively added to the reactor equipped with a thermometer and a reflux condenser, and indium trichloride (8.85 g, 40 mmol) was added to the reactor at one time, The temperature of the reaction system rose to 80°C, the boiling point of acetonitrile, and refluxed for 4 hours after the indium trichloride was completely dissolved. 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 2.62 g of polycarbonate anti-high temperature degradation agent A with a yield of 97%.
