Syntheses of heteroleptic 1,8-bis(phosphino)naphthalenes and 5,6-bis(phosphino)acenaphthenes were attempted using several synthetic strategies. Reaction of aryllithium with triphenylphosphite gave ArP(OPh)2 (Ar = substituted naphthalene or acenaphthene), which was transformed into ArP(CF3)2, using a nucleophilic trifluoromethylation reaction with Me3SiCF3/CsF. The importance of the correct choice of
使用几种合成策略尝试合成杂合的1,8-双(膦基)萘和5,6-双(膦基)ac啶。芳基锂与亚磷酸三苯酯 给了 ArP(OPh)2 (氩气 =替代 萘 或者 ena),然后通过与Me 3 SiCF 3 /的亲核三氟甲基化反应将其转化为ArP(CF 3)2。脑脊液。讨论了正确选择溶剂对三氟甲基化反应的重要性。ArP(CF 3)2与有机锂 阻碍了第二个的附件 膦 有机骨干网的功能。 四苯氧基乙烯在三氟甲基化反应中以少量的副产物形式获得了β-环糊精。所选的新化合物通过单晶X射线衍射进行表征。
