✦ Synopsis

Oligomers containing from 2 to 6 thiophene units attached by their 2 and 5 positions were synthesized unambiguously by iodine oxidation of a suitable ate complex obtained by stepwise reactions of 9-BBN with methanol, a 2_lithiothiophene, boron trifluoride etherate, and a second 2-lithiothiophene. This is a one-pot procedure, carried out under nitrogen between -80 'C and 0 C.
