Furan reacts with BuLi and halosilanes to give mono-(1, 5, 7), bis-(2, 6), tris-(3), and tetrakis(2-furanyl)silanes (4); (Fu-R; R = SiMe2Cl (1), SiisoPr7F (5), Si1Bu2F (7); Fu-R-Fu; R = SiMe2 (2), SiisoPr2 (6); Fu3Si1Bu (3), Fu4Si (4)), 2,5-Bis(silyl)furans (8, 9) are obtained in the reaction of dilithiated furan and fluorosilanes in a molar ratio 1:2 (R-Fu-R; R = SiisoPr2F (8), Si1Bu2F (9), 1,4-Bis(di-terf-butylfluorosilyl)butadiyne (10) is formed from furan four equivalents of BuLi, and two equivalents of F2Si1Bu2. 10 reacts with KOH to give 1Bu2(OH)Si-C≡C-C≡C-Si1Bu 2OH (11). Substitution of the fluorine atoms of 5 and 7 by a NH2 group occurs with MNH2 (M = Li, Na). 12 and 13 are obtained. The reaction of 13 with BuLi and 1Bu2SiF2 leads to the formation of FuSi1Bu2NHSi1Bu2F (14) and 1Bu2Si(NH-Si1Bu2Fu)2 (15). The lithium derivative of 14 crystallizes as monomer from THF as FuSi1Bu2N(LiTHF2)Si1Bu2F and as a dimer containing a four-membered ring (16) from n-hexane (FuSi1Bu2NSi1Bu2LiF)2 (17). The crystal structures of 4, 10, 16, 17 have been determined.

Organolithium reagents RLi can cleave Si-C and Ge-C bonds in heterylsilanes and -germanes substituting furyl, dihydrofuryl and dihydropyranyl groups for the organolithium residue R.
