Abstract: New ways to synthesize 1,2- and 1,3-bis(silyl)indoles are shown in this paper and new members of these classes of substances are isolated and characterized The crystal structures of the lithium salt of 2-(tert-butyldimethylsilyl) indole (1) (space group P21/c, a = 1018.0(3), b = 1651.4(3), c = 1648.9(5) pm, β = 94.54(3)°, V = 2.763(1) nm3, ρcalc = 1.090 Mg/m3, Z = 4, 4831 reflections, RI (I > 2σ(I) = 0.052, wR2 (all data) = 0.152) and 1-(di-tert-butylfluorosily1)-2-(trimethylsilyl)indole(4) (space group P21/c, a = 1015.5(1), b = 1733.5(3), c = 1261.3(2) pm, β = 105.61(2)°, V = 2.1385(5) nm3, ρcalc = 1.086 Mg/m3 , Z = 4, 2779 reflections, R1 (I > 2σ(I) = 0.055, wR2 (all data) = 0.163) are reported. Furthermore the first examples of bis(indo1-3-y1)silanes (9, 10) are isolated. Specific reactions for the desilylation of 1,3-bis(sily1)indoles are discussed.
