Yield	Reaction Conditions	Operation in experiment
	With potassium tert-butylate; In N,N-dimethyl-formamide; at 120℃; for 3.0h;	A solution of Int-lb (6.0 g, 14 mmol) and t-BuOK (1.73 g, 15.4 mmol) inDMF (20 mL) was stirred at 120 C for 3 hr. Then the mixture was cooled and poured into 60 mL of ice-water. The mixture was then extracted withdichloromethane three times, the combined organic layers were concentrated in vacuo, and the crude products were purified by chromatography on silica gel to give an inseparable mixture compound Int-lc and Int-ld (87%). 1H MR (CDC13) δ: 7.01- 7.05 (m, 4 H), 6.72-6.74 (d, J=8.4 Hz, 2 H).

Yield	Reaction Conditions	Operation in experiment
95%	With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,4-dioxane; water; for 8.0h;Heating;	<strong>[39073-07-9]2,7-dibromodibenzo[b,e][1,4]dioxine</strong> (137g, 0.400mol), phenylboronic acid (49g, 0.400mol) and Pd(PPh3)4 (23.1g, 0.02mol) in a flask, where the put 2M Na2CO3 saturated solution (600ml) and 1,4-dioxane (2L) was dissolved. After the resulting mixture was stirred under heating for 8 hours. After the reaction, distilled water the organic layer was extracted with ethyl acetate. obtained compound to the organic layer was dried over Na2SO4 and purified by distillation under reduced pressure, and then purified by column chromatography 2-bromo-7-phenyldibenzo[b,e][1,4]dioxine to give the (129g, 95% yield).
