实验过程

As shown in Scheme 2, 7-bromo-9H-fluoren-2-ylamine is reacted with 1-iodobutane to form (7-bromo-9,9-dibutyl-9H-fluoren-2-yl)-dibutylamine (21). Then, (7-bromo-9,9-dibutyl-9H-fluoren-2-yl)-dibutylamine (21) is reacted with 5-formyl-2-thiopheneboronic acid by Suzuki coupling reaction to obtain 5-(9,9-Dibutyl-7-dibutylamino-9H-fluoren-2-yl)-thiophene-2-carbaldehyde (22a). Finally, in acetonitrile, 5-(9,9-Dibutyl-7-dibutylamino-9H-fluoren-2-yl)-thiophene-2-carbaldehyde (22a) is reacted with cyanoacetic acid by using piperidine as a catalyst, to obtain 2-Cyano-3-[5-(9,9-dibutyl-7-dibutylamino-9H-fluoren-2-yl)-thiophen-2-yl]-acrylic acid (23a).
