Unprecedented Demonstration of Regioselective SEAr Reaction giving Unsymmetrical Regioregular Oligothiophenes
Aromatization of 4-cyano-3-oxotetrahydrothiophene by sulfuryl chloride gives the new building block 4-cyano-3-pyrrolidylthiophene, which forms unsymmetrical regioregular oligothiophenes with a strict alternation of the donor and acceptor groups along the conjugated system. The self-coupling reactions that form the oligomers are shown to proceed by a regioselective electrophilic aromatic substitution mechanism involving a stabilized Wheland intermediate. First alternate: Regioregular oligothiophenes based on the 3-pyrrolidyl-4-cyanothiophene building block, with a strict alternation of the donor and acceptor groups along the conjugated backbone, have been prepared in one step. The mechanism of formation of the oligomers corresponds to a regioselective self-electrophilic aromatic substitution (self-SEAr) involving a stabilized Wheland intermediate.
