Embodiment 1
[0036] Synthesis of Aminotetraphenylmethane
[0037] Add 14.3g of triphenylmethanol, 7.7mL of aniline, 200mL of acetic acid and 28mL of concentrated hydrochloric acid into a 500mL flask, heat at 120°C for 8 hours, cool to room temperature, and neutralize with 6M sodium hydroxide to obtain aminotetraphenyl Methyl methane white powder. The pure product can be obtained by column chromatography with petroleum ether / dichloromethane=1:1 eluent.
Embodiment 2
[0039] Synthesis of Tetraphenylmethane
[0040] Add 850.9mg of tetraaminophenylmethane, 63.8mL of ethanol and 8.6mL of concentrated sulfuric acid into a 250mL flask, mix and cool to -10°C, add 1.4mL of isoamyl nitrite, stir for 30min, then add 6.5mL of 50% Hypophosphorous phosphoric acid, and then heat up to 80°C for 20 minutes to obtain yellow tetraphenylmethane.
Embodiment 3
[0042] Synthesis of Tetrabromophenylmethane
[0043] Add 5.0g of tetraphenylmethane into a 250mL flask, cool to 0°C, add 10mL of bromine water dropwise, then slowly warm up to room temperature and react for 20 minutes, then cool to -78°C, add 50mL of ethanol, warm up to room temperature, and add to the sodium sulfite solution and excess bromine water to obtain a dark yellow product.
