两种水相中制备1,1’-联-2,2’-二萘酚的方法

Two Ways to Synthesise Racemic BINOL in Aqueous Phase

介绍了两种在水相中利用2-萘酚氧化偶合制备外消旋1,1’-联-2,2’-二萘酚的催化剂,并对不同反应条件下的产率进行了研究。结果表明[Cu(NH3)4]2+作催化剂时,产率可达97%;而新制的Cu(OH)2作催化剂时,产率则达到了91%。

Two different catalysts for oxidative coupling of 2-naphthol to give racemic 1,1 ＇-binaphthene-2, 2＇ -diol （BINOL） were introduced and the yields in different conditions were studied, When [ Cu（NH3 ）4 ]^2＋ and freshly prepared Cu（OH）2 were used as catalysts, the yields were 97 and 91%, respectively.
