Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 105309-59-9, name is Tetrakis(4-bromophenyl)methane, A new synthetic method of this compound is introduced below., Application In Synthesis of Tetrakis(4-bromophenyl)methane
(a) Add tetra-[4-bromo-phenyl]methane 0.636 g (1 mmoL) and tetrakistriphenylphosphine palladium 0.18 g to a 50 mL two-necked round bottom flask and add toluene/tetrahydrofuran mixed solvent 20 mL under a vacuum of nitrogen. (volume ratio is 1:1), stir and dissolve uniformly, then inject 3-butylthiophene tributyl group 3.642g (8mmoL), raise the temperature to 140C, and react for 24 hours under light-proof conditions. After the reaction was completed, the mixture was extracted with methylene chloride, and the extract was spin-dried and separated by a column. Silica gel was used as a filler, and petroleum ether and methylene chloride (4:1 by volume) were used as eluent to give a pale yellow product (0.39 g). The yield is 40%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
