Abstract The reactivity of the 2‐bromothiapseudophenalenone ( 1 ) 2‐bromo‐5 H ‐naphtho[1,8‐ bc ]‐thiophen‐5‐one and of the 2‐bromothiapseudophenalenium salt ( 2 ) 2‐bromo‐5‐ethoxynaphtho‐[1,8‐ bc ]thiolium‐tetrafluoroborate towards the N ‐nucleophilic compounds R‐NH 2 ( 3 ) or R‐NH‐NH 2 and the C ‐nucleophilic molecules e.g. , malonodinitrile, barbituric acid was of interest. We obtained the substituted hydroxyiminothiapseudophenalenone derivatives 4a‐g, 6a‐g, 7, 8, 9, 11a‐o, 12 and 14 .
