The synthesis of substituted benzoselenopheno[2,3-b]benzoselenophens from 1,1-diarylethylenes was achieved in much higher yields with diselenium dichloride than with seleninyl chloride. 1,1-Bis-(2,4-dimethylphenyl)-ethylene with either selenium tetrachloride or diselenium dichloride yielded the corresponding 2,2-diarylvinyl selenide; reactions of other diarylethylenes with selenium tetrachloride or
用二氯化二硒比用硒基氯以高得多的产率由1,1-二芳基乙烯合成取代的苯并硒吩[2,3- b ]苯并硒酚。1,1-双-(2,4-二甲基苯基)-乙烯与四氯化硒或二氯化二硒产生相应的2,2-二芳基乙烯基硒化物;其他二芳基乙烯与四氯化硒或四溴化硒的反应生成无硒产物。扩大与亚硒酰氯的反应以产生二-1-苯并硒基苯并[2,3- b:2',3'- b ']苯并二硒酚。
