The two isomeric bis(isocyanates) 4,12- and 4,16-di-isocyanato[2.2]paracyclophane, 16 and 28, have been prepared from their corresponding diacids by simple routes. The two isomers are versatile intermediates for the preparation of various cyclophanes bearing substituents with nitrogen-containing functional groups, e.g., the pseudo-ortho diamine 8, the bis secondary amine 23, and the crownophanes 18
已经通过简单的路线由它们的相应二酸制备了两个异构体双(异氰酸酯)4,12-和4,16-二-异氰酸根合[2.2]对环环烷16和28。这两种异构体是通用中间体,用于制备带有带有含氮官能团的取代基的各种环烷,例如伪邻二胺8,双仲胺23和冠环烷18和19。已经通过X射线结构分析对18、19、22、26、28)进行了表征。
