2,2'- (2a) and 3,3'-bifuran (3), hitherto only accessible by ring-forming syntheses in small yields, and the unknown compounds all-α-terfuran (2b) and all-α-quaterfuran (2c) have been prepared by convenient ring-connecting syntheses in 85, 46, 16, or 53percent-yield, respectively.Lithiation of 2a and subsequent reacting with iodine afforded 5-iodo-2,2'-bifuran (6b, 46percent).According to competition experiments acidity against n-butyllithium is increasing in the sequence furan 2a 2b.
