News from Silicone An Isomer of Hexasilabenzene and A Metal-Silicon Triple Bond

摘要

Novel, stable, isolable, and storable key intermediates were recently introduced into organosilicon chemistry. These compounds have the potential to broaden significantly the synthetic chemistry of low-coordinated silicon. This is demonstrated by two recent landmark achievements: The characterization of an unprecedented isomer of hexasilabenzene (1) and by the synthesis of the molybdenum-silylidyne complex 2.
