  The reaction of hexachlorodisilane, Si2Cl6, With six equivalents of lithium alkynides, Li-Cequivalent toC-R (R = Bu, SiMe3) led to hexa(1-alkynyl)disilanes Si-2(Cequivalent toC-R)(6) [R = Bu (1), Me3Si (2)], whereas the reaction with the propynide Li-Cequivalent toC-Me, under analogous conditions, afforded only tetra(1-propynyl)silane, Si(Cequivalent toC-Me)(4) 3. The molecular structures of 2 and 3 were determined by X-ray analysis. Surprisingly, in the course of 1,1-ethylboration of the disilanes land 2 the Si-Si bond is cleaved and finally monosilanes such as the substituted 5-silaspiro[4.4]nona-2,4,6,8-tetraenes 4 and 5, respectively, were obtained, compounds analogous to 6 which previously have been shown to result from 1,1-ethylboration of tetra(1-alkynyl)silanes Si(Cequivalent toC-R)4 such as 3 (R = Me). In the case of the reaction of 2 with triethylborane, it proved possible to detect an intermediate 7, in which the disilane structure is still retained and, according to NMR data (H-1, B-11, C-13, Si-29-NMR), only two of the six Cequivalent toC-SiMe3 moieties have reacted.
