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 = SiMe 2 Cl (1), SiisoPr 2 F (5), Si t Bu 2 F (7); Fu-R-Fu; R = SiMe 2  (2), SiisoPr 2  (6); Fu 3 Si t Bu (3), Fu 4 Si (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 = SiisoPr 2 F (8), Si t Bu 2 F (9), 1,4-Bis(di-tert-butylfluorosilyl)butadiyne (10) is formed from furan four equivalents of BuLi, and two equivalents of F 2 Si t Bu 2 . 10 reacts with KOH to give  t Bu 2 (OH )Si-C =C -C =C-Si t Bu 2 OH (11). Substitution of the fluorine atoms of 5 and 7 by a NH 2  group occurs with MNH 2  (M = Li, Na). 12 and 13 are obtained. The reaction of 13 with BuLi and  t Bu 2 SiF 2  leads to the formation of FuSi t Bu 2 NHSi t Bu 2 F (14) and  t Bu 2 Si(NH-Si t Bu 2 Fu) 2  (15). The lithium derivative of 14 crystallizes as monomer from THF as FuSi t Bu 2 N(LiTHF 2 )Si t Bu 2 F and as a dimer containing a four-membered ring (16) from n-hexane (FuSi t Bu 2 NSi t Bu 2 LiF) 2  (17). The crystal structures of 4, 10, 16,17 have been determined.
