Yield:-
Reaction Conditions:
with tetrakis(triphenylphosphine) palladium(0);potassium carbonate in tetrahydrofuran at 80; for 12 h;
Steps:
4
Add 100mmol of 2,3-dichloroquinoxaline, 100mmol of 2-naphthaleneboronic acid, 41.4g of potassium carbonate (300mmol), 800ml of THF, 200ml of water and Pd(PPh3)4 into the reaction flask, and react at 80 for 12h After the reaction is complete, stop the reaction, and cool the reactant to room temperature, add water, filter, and wash with water. The solid obtained is recrystallized and purified with toluene to obtain a white powder M3, where the addition amount of Pd(PPh3)4 is 2, 1 mol% of 3-dichloroquinoxaline;
