Abstract Phthalocyanines, aromatic macrocycles constituted of four isoindole subunits through aza bridges, have been widely studied in the last few years due to their unusual physical properties. Porphyrins, phthalocyanines and related macrocycles modified by the attachment of peripheral substituents, have found vast applications in diverse areas such as chemical sensors. When 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) (1) firstly was fused a deep green product 2. The same reaction when repeated by route (B) in which 1 was fused with 1,4-diazabicyclo [2.2.2]octane (DBO) at 200 oC, then ethylene glycol was added and the reaction was continued heating for about 10 hrs under nitrogen gas they gave identical product 2. Yield was improved from 35% in case of route (A) to 71% in case of route. |
