A series of (1-propynyl)arenes were prepared by one-pot double elimination reaction of ethyl sulfone, aromatic aldehyde and chloro diethylphosphate in THF with a base such as BuLi and T-BuOK. A propargyllithium which was prepared by treatment of (1-propynyl)arene with BuLi in the presence of 1,3-dimethyl-3,4,5,6-tetrahydro-2(1 H)-pyrimidinone (DMPU) reacted with aromatic aldehyde, chloro diethylphosphate
通过乙砜、芳香醛和氯代磷酸二乙酯在四氢呋喃中与BuLi、T-BuOK等碱进行一锅双消反应制备了一系列(1-丙炔基)芳烃。在 1,3-二甲基-3,4,5,6-四氢-2(1 H)-嘧啶酮 (DMPU) 存在下用 BuLi 处理(1-丙炔基)芳烃与芳香醛反应制备的炔丙基锂,氯二乙基磷酸酯和 T-BuOK 得到(4-芳基丁-3-烯-1-炔基)芳烃。如此制备的烯炔的光致发光在溶液和固态中均被记录。
