A simple and efficient synthesis of tribenzohexadehydro[12]annulene and its derivatives was carried out using coupling reaction of acetylenes with iodoarenes in the presence of catalytic amounts of CuI and PPh,, together with three equivalents of K 2 CO 3 in DMF. This synthetic procedure was applied to the synthesis of a large annulenoannulene derivative.
在催化量的 CuI 和 PPh 以及三当量的 DMF 中的 K 2 CO 3 存在下,使用乙炔与碘代芳烃的偶联反应进行了三苯并六氢[12]环烯及其衍生物的简单有效合成。该合成程序适用于合成大环烯基环烯衍生物。
