(7-azabenzonorbornadienes) and reduced derivatives is described together with 1,4-dihydro-1,4- and 9,10-dihydro-9,10- iminoanthracenes. VT NMR studies lead to unambiguous assignment of invertomer preferences; changes in the invertomer ratios and nitrogen inversion barriers are investigated as the electronic and steric environment is modified by variation of substituents in the carbon skeleton and at nitrogen
描述了一系列N-烷基1,4-二氢-1,4-亚氨基萘(7-氮杂苯并降冰片二烯)和还原衍生物与1,4-二氢-1,4-和9,10-二氢-9的合成,10-亚氨基蒽。VT NMR研究可明确确定内向异构体的偏好。随着碳骨架中和氮原子上取代基的变化而改变了电子和空间环境,研究了转化体比率和氮转化障碍的变化。
