Selective synthesis of 1,1′-binaphthalene derivatives by oxidative coupling with TiCl4
摘要:
Oxidative coupling of naphthalene compounds with TiCl4 in nitromethane under mild conditions gives symmetrical 1,1'-binaphthyls in good yields, The method is particularly useful when applied to substrates with electron donating groups, (C) 2000 Elsevier Science Ltd. All rights reserved.
reaction of 1-alkoxynaphthalenes 1 with alumina-supported copper(II) bromide or copper(II) chloride gave dimers, 4,4′-dialkoxy-1,1′-binaphthyls 3, as major products, and with Kieselguhr-supported copper(II) bromide afforded 1-bromo-4-alkoxynaphthalenes 2, while the reaction of 2-alkoxynaphthalenes 4 with alumina- or Kieselguhr-supported copper(II) bromide gave preferentially 1-bromo-2-alkoxynaphthalenes
1-烷氧基萘 1 与氧化铝负载的溴化铜 (II) 或氯化铜 (II) 反应生成二聚体 4,4'-二烷氧基-1,1'-联萘 3,作为主要产物,并与硅藻土负载的铜反应(II) 溴化物得到 1-bromo-4-alkoxynaphthalenes 2,而 2-alkoxynaphthalenes 4 与氧化铝或硅藻土负载的溴化铜 (II) 反应优先得到 1-bromo-2-alkoxynaphthalenes 5。
