leading to 6ba and 6da. Bithiophene 6da was transformed into
terthiophene 7dac in 55% yield by reaction with 5c.

In summary, we have shown that regiocontrolled metalation
of 3-substituted thiophenes using the KnochelÀHauser base 1 or
a combination of catalytic TMPH and Grignard reagent as a
selective metalating agent allows them to undergo reaction with
bromothiophenes to form head-to-tail (HT)-type bithiophenes.
By repetition of this reaction, iterative growth of a thiophene unit
by single-step extensions was revealed to be operative, leading to
HT oligothiophenes, and with this method, a wide variety of
oligothiophene derivatives can be synthesized in an extremely
facile manner.
