Functionalizations of diamantane, triamantane, and tetramantane with electrophilic reagents (Br2, nitric acid) lead to various apical and medial disubstituted products that were separated and characterized individually. The highly desirable and otherwise inaccessible thermodynamically more stable apical bis-derivatives were obtained with high preparative yields through acid catalyzed isomerizations
使用亲电试剂(Br2、硝酸)对金刚烷、三金刚烷和四金刚烷进行官能化会产生各种顶端和中间双取代产物,这些产物被单独分离和表征。通过酸催化异构化以高制备产率获得了非常理想的和否则无法获得的热力学更稳定的顶端双衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
