Abstract

Abstract This study details a highly significant improvement in the synthesis of 1,6-disila[4.4.4]propellane (1) through the implementation of a mechanistically rationalized fluorosilane route. This efficiency represents a more than 20-fold enhancement over the previously reported method (4% yield). Structural analysis by single-crystal X-ray diffraction revealed its unique columnar packing arrangement in the solid state.
