在室温下 K / (NH~2CH~2)~2中, 氯萘和4-溴二苯与碳负离子发生Photo-S~R~N1反应, 阴碳离子来自乙酸叔丁酯,吗啡丙酯, 乙腈或丙腈. 与K / NH~3体系中的Photo-S~R~N1反应相比, ArNu的产率减少到50%左右, 而ArH的产率增加.

关键词: 钾, 阴碳离子, 光诱导S~R~N1反应, 乙二胺体系

Photo-S~R~N1 reactions of chloronaphthalene, 4-bromobiphenyl with carbanions derived from t-butyl acetate, morphine propionate, acetonitrile and propionitrile, operated in K / (NH~2CH~2)~2 at room temperature . In comparison with the Photo-S~R~N1 in K / NH~3, the yield of ArNu decreased to moderate level (ca. 50%) while the amount of ArH increased dramatically (yield, 20-40%).

Key words: CARBANION, POTASSIUM
