Optically pure 7,7â²-ethylenedioxy-1,1â²-biisoquinoline 2and the 7,7â²-(5-methoxy-m-xylylenedioxy) analogue 3 are prepared; their chelation to rhodium(I) takes place with complete retention when (R)-(â)-3 is treated with [RhCl(cod)]2 to give [Rh(R)-(â)-3}(cod)]+, while a similar reaction of (+)-2gives a racemic complex [Rh(2)(cod)]+; both RhIcomplexes are structurally characterized by an X-ray diffraction study.
制备光学纯的7,7α-亚乙基二氧基-1,1α-二
异喹啉2和7,7α-(5-甲氧基-间亚二
甲苯基)类似物3;当 (R)-(→)-3 用 [RhCl(cod)]2 处理时,它们与
铑 (I) 发生螯合并完全保留,得到 [Rh(R)-(→)-3 }(cod)]+,而 (+)-2 的类似反应给出外消旋复合物 [Rh(2)(cod)]+;两种 RhI 复合物均通过 X 射线衍射研究进行了结构表征。
