“…Not only the nature of the end groups on the 1,3-diacetylenes but also the manner in which the silylene 7 is generated are decisive for the course of the reaction. When, instead of 6 , the silirane 30 is subjected to photolysis, the thermally stable bis(ethynyl)silane 32 is initially formed and furnishes the bicyclic compound 33 upon further irradiation . The photolysis of 6 in the presence of the octa-1,3,5,7-tetrayne 34 is even more transparent and results in the formation of three isolable products.…”

In less than three decades the chemistry of low-coordinated compounds of the heavier elements of group 14 has made unforeseen and unprecedented advances. In the meantime not only have homonuclear double bonds been realized between all elements of this group but also the first examples of compounds analogous to the alkynes have been isolated. Similarly, syntheses of molecules containing heteronuclear bonds have been achieved. Analogues of the allenes as well as the first example of a spiropentasiladiene are of particular interest. The present short review covers mainly work done in the author's laboratories together with other relevant reports from the literature. It begins with the synthesis of hexa-tert-butylcyclotrisilane, which is cleaved photochemically into a short-lived silylene and a marginally stable disilene; in subsequent reactions both of these species can undergo cycloadditions to furnish a broad palette of mostly novel ring systems. Furthermore, the first molecules with conjugated SiSi, GeC, and GeGe double bonds have been obtained and their reactivities examined. The isolation of the first diplumbenes and a cyclotriplumbane exhibiting an unusual bonding situation as the first homocyclic compound of lead constitute a provisional end of these developments.

“…The 29 Si-NMR spectrum featured three signals of was confirmed by X-ray crystallography. [16] Further treatment of the dialkynylsilane 17 with the silirane 2 led to an equal intensity at δ ϭ Ϫ2, Ϫ19, and Ϫ22.…”
