title: Regioselective electrophilic access to naphtho[1,2-b:8,7-b']- and -[1,2-b:5,6-b']dithiophenes.
abstract: A two-step one purification access to dichloronaphtho[1,2-b:8,7-b'] and [1,2-b:5,6-b']dithiophenes 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 methodology.
