Synthesis of 7,8:13,14-dibenzo-2,9,11-trisdehydro[16]annulene-1,4-dione is described. Attempts to prepare diaza[18]annulene derivatives by ring expansion of the dibenz[16]annulenedione and its dimethyl analog are also described. Examination of 1H NMR spectra indicates that the dibenz[16]annulenedione shows no ring current effect.
描述了7,8:13,14-二苯-2,9,11-三脱氢[16]环烯-1,4-二酮的合成。也描述了通过二苯[16]环烯二酮及其二甲基类似物的环扩张来尝试制备二氮[18]环烯衍生物。对1H NMR谱的检查表明,二苯[16]环烯二酮没有环电流效应。
