摘要
以氯化苄和对硝基氯苄为原料,经Wittig反应合成中间体:2-甲氧基-二苯乙烯和2-甲氧基-4'-硝基-二苯乙烯.后者经还原反应、重氮化反应后,在氢氧化钠存在下与前者反应生成最终产品荧光增白剂FP(4,4'-双-2-(甲氧基苯乙烯基)联苯).为该类荧光增白剂的合成开辟了一条新路线.
Methoxystilbene and 2-methoxy-4'-nitrostilbene were synthesized from benzyl chloride and nitrobenzyl chloride by the Wittig reaction, and used as intermediates for the synthesis of the final product fluorescent whitener FP(4,4'-bis(2-methoxystyryl)biphenyl) via reduction and diazotisation of the latter followed by reaction with the former in the presence of NaOH. A new synthesis route was created for the fluorescent whiteners in this kind.
