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。

Unlike the related noncyclic amidines which are broad-spectrum cestocides, a number of 2-imidazolines substituted in the 2 position by alkoxyaryl groups were not highly active in screening tests against the mouse tapeworms Hymenolepsis nana and Oochoristica symmetrica. Certain of the 2-(4-alkoxynaphthyl)-2-imidazolines and 2-(6-alkoxy-2-naphthyl)-2-imidzolines, however, had activity interpreted as antidepressant in the mouse. This activity paralleled in vitro irreversible inhibitory activity against mouse brain MAO for those where no substitution is present on the imidazoline ring. This irreversibility probably has a different origin from that postulated to explain the irreversible MAO inhibition of proparglic, cyclopropyl, and other "chemically reactive" MAO inhibitors.
