Abstract
Ab initio calculations (3-21G(∗)//STO-3G) indicate planar, aromatic 1,4-disilabenzene (5), its Dewar form (6), and a silylene isomer (7) to have rather similar thermodynamic stabilities. While the corresponding monosilabenzene isomers have larger energy differences, both sets of compounds illustrate the reduced aromaticity of the silabenzenes and the relative weakness of π-Si-C over π-C-C and σ-Si-Si bonds.
