Abstract

Two stereoisomers of the first stable bis(silacyclopropa)benzenes (1a, 1b) were successfully synthesized by the reaction of Tbt(Dip)SiLi2 (3) [Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Dip = 2,6-diisopropylphenyl] with 1,2,4,5-tetrabromobenzene. The molecular structures of 1a and 1b were discussed on the basis of the X-ray structural analyses.
