Viglianisi, Caterina published the artcileRegioselective Electrophilic Access to Naphtho[1,2-b:8,7-b’]- and -[1,2-b:5,6-b’]dithiophenes, COA of Formula: C12H6F6O6S2, the publication is Journal of Organic Chemistry (2013), 78(7), 3496-3502, database is CAplus and MEDLINE.
A two-step one purification access to dichloronaphtho[1,2-b:8,7-b’] and [1,2-b:5,6-b’]dithiophenes, e.g. I and II, using bis-alkylnaphthyl alkynes and phthalimidesulfenyl chloride as starting materials has been developed. The functionalization of the carbon-chlorine bonds allowed further modification of NDT core, broadening the potential of the methodol.
