Abstract
In summary, the 1,2-diaryldisilyne 1 showed high reactivity with alkynes, especially unhindered alkynes. Both polar and nonpolar alkynes reacted with 1 to give 1,2-disilabenzene as the major product. Crystal structure analysis showed that the central ring of 1,2-diaryl-1,2-disilabenzene 2 is almost planar, and most notably, the Si–Si bond has significant trans-bent character. Evidence supporting the aromatic structure of 2 was collected by both experimental and theoretical means.
