Abstract
The first stable 9-silaanthracene, 5, bearing an efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt), was successfully synthesized by the reaction of the corresponding silyl triflate, 7, with a 1.0 M amount of lithium diisopropylamide. The aromaticity of 5 is discussed on the basis of the NMR, UV/vis, and Raman spectra, X-ray structural analysis, and theoretical calculations.
