3′,5′-Di-tert-butyl-4-chloro-4′-hydroxy-1,1′-biphenyl was obtained selectively by an electro-induced SRN1 reaction, starting from 1,4-dichlorobenzene and 2,6-di-tert-butylphenoxide. The product was then further substituted to give a phosphine and (phosphoniohenyl)phenoxide zwitterions or carboxylated to obtain 3′,5′-di-tert-butyl-4′-hydroxy-1, 1′-biphenyI-4-carboxylic acid.
通过电诱导的SRN1反应,选择性地获得了3′,5′-二叔丁基-4-氯-4′-羟基-1,1′-联苯,起始物为1,4-二氯苯和2,6-二叔丁基苯氧化物。随后,将产品进一步取代,生成了膦和(膦基苯)苯氧负离子或羧化,从而获得了3′,5′-二叔丁基-4′-羟基-1,1′-联苯-4-羧酸。
