Energy transfer proceeds in orthogonal dyads in contrast to Förster’s theory and cannot be prohibited even by rigid interconnecting cage compounds such as cubane or diamantane.
A new polycyclic diamine, 1,6-diaminodiamantane, was synthesized starting from 1,6-dibromodiamantane. The reaction of 1,6-dibromodiamantane with acetonitrile using H2SO4 as catalyst afforded 1,6-diacetamidodiamantane in 72% yield. The reaction of 1,6-diacetamidodiamantane with NaOH afforded 1,6-diaminodiamantane in 50% yield.
从1,6-二溴二金刚烷开始合成了一种新的多环二胺1,6-二氨基二金刚烷。1,6-二溴二金刚烷与乙腈的反应,使用H 2 SO 4作为催化剂,以72%的收率得到1,6-二乙酰胺基二金刚烷。1,6-二乙酰氨基二金刚烷与NaOH的反应以50%的产率提供了1,6-二氨基二金刚烷。
