So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Rasanu, Nicolae; Maior, Ovidiu researched the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8 ).Application In Synthesis of 5-Iodo-2-furaldehyde.They published the article 《Synthesis based on formylfuro(2,3-b) benzothiachromone》 about this compound( cas:2689-65-8 ) in Revue Roumaine de Chimie. Keywords: furobenzothiachromone. We’ll tell you more about this compound (cas:2689-65-8).
ο[(5-Formyl-2-furyl)thio]-benzoic acid, obtained from reaction of ο-mercaptobenzoic acid with 5-iodofurfural, cyclized (polyphosphoric acid) to give the furobenzothiachromone I (R = CHO), which when treated with HONH2 gave I (R = CH:NOH). The latter was converted (Ac2O) to the nitrile I (R = CN), hydrolysis (polyphosphoric acid) of which gave the expected amide I (R = CONH2).
From this literature《Synthesis based on formylfuro(2,3-b) benzothiachromone》,we know some information about this compound(2689-65-8)Application In Synthesis of 5-Iodo-2-furaldehyde, but this is not all information, there are many literatures related to this compound(2689-65-8).
