The possibility of the heterocyclization of vic-alkynylanthraquinonediazonium salts with the formation of a 5- or 6-membered ring, depending on the reaction conditions, is established. The heterocyclization of 2-alkynyl-9,10-anthraquinone-1-diazonium salts to form 1H-naphtho[2,3-h]cinnoline-4,7,12-triones is reported.
根据反应条件,确定了形成5-或6-元环的vic-炔基蒽醌二重氮盐杂环化的可能性。据报道2-炔基-9,10-蒽醌-1-重氮盐的杂环形成1 H-萘[2,3 - h ] cinnoline-4,7,12-三酮。
