Yield	Reaction Conditions	Operation in experiment
80%	With tris-(dibenzylideneacetone)dipalladium(0); tri-tert-butyl phosphine; 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl; sodium t-butanolate; In o-xylene; toluene; at 160℃; for 48h;	Pd2 (dba) 3 357.3 mg (0.39 mmol) and t-Bu3P mg 157.9 (0.78 mmol) of o-xylene dissolved in 50 ml after 10 minutes at room temperature in agitation. 4H-dithiol in no [3,2-b: 2 ', 3'-d] pyrrole 8.23 g (46 mmol), 3,6 - dibromo -9-phenyl-9H-carbazole 7.98 g (20 mmol) It was added, and t-BuONa 2.25 g (23.41 mmol) and reflux was stirred for 48hours at 160°C. Cold distilled water was added to 20 ml After completion of the reaction and extracted with ethyl acetate. The solvent was evaporated and dried over magnesium sulfate and filtered. After the compound was purified by column chromatography through 135 4,4 '- (9-phenyl -9H- carbazole-3,6-diyl) bis (4H- the furnace dithiane [3,2-b: 2', 3'-d ] pyrrole) to give 9.55 g (80percent yield).
66%	With palladium diacetate; tris-(o-tolyl)phosphine; sodium t-butanolate; In toluene;	Afterward, the Intermediate E and Intermediate D were used to perform Buchwald-Hartwig cross-coupling to synthesize 3.65 g (66percent) of Compound 109.
