Article abstract of DOI:10.1246/cl.1986.1643

Persilylcyclotetrasilanes of the type <(R¹R²R³Si)2Si>4 (R¹=R²=R³=Me; R¹=Et, R²=R³=Me) were readily obtained by the reductive coupling of the corresponding 2,2-dibromo-1,1,1,3,3,3-hexaalkyltrisilanes using sodium; the Si4 frameworks of these persilyl compounds act as much more intense chromophore than those of peralkyl analogues.
