“…412 For example, in organosilicon chemistry, many unsaturated compounds, such as silaaromatics (silabenzene), 1322 trisilaallene (R 2 Si=Si=SiR 2 ), 2327 and disilyne (RSi¸SiR), 2834 have been synthesized by taking advantage of the steric protection by the appropriate bulky groups. 35 The bulky protecting groups so far developed can be categorized into three types, i.e., aryl, 2,3,1319,21,22,34 alkyl, 1,2327 and silyl 20,2833 groups. Among them, the bulky aryl groups have been the most widely used in this chemistry.…”

A series of octa-R-substituted bromo-s-hydrindacenes, "Rind-Br," have been synthesized by a sequence of the Lewis acid catalyzed intramolecular FriedelCrafts reaction, bromination and vice versa. Their structural features and physical properties depend on the eight R-substituents at the four benzylic positions on the s-hydrindacenyl skeleton. The molecular structures of the Rind-Br have been confirmed by X-ray crystallography, indicating the unique structural diversities of the bulky Rind groups.

“…This pioneering work done in Lappert's group was merely a harbinger of what was to come. The results that made much of the chemical community truly take note were the nearly concurrent reports of both a silene (Si=C) 4 and disilene (Si=Si) 5 in 1981, both of which were stable in solution and in the solid state. In the case of the silene TMS 2 Si=C(OTMS)(Ad) (3) (TMS: trimethylsilyl, Ad: 1-adamantyl) both electronic and steric stabilization was highlighted.…”

Unsaturated main group 14 species have unique properties and reactivity compared with their organic analogues. The isolation of stable disilynes, one of the most recent and intriguing additions to the catalog of unsaturated main group species, has opened the way for further studies into the differences between organic molecules and their heavy analogues. Since the isolation of the first disilyne, the reactivity and properties of these species has been the subject of numerous studies. Herein, the recent developments and results pertaining to the reactivity of disilynes are discussed.

“…The first reliable reports on stable compounds with heavier double bonds to silicon, however, only appeared in 1981. Since these milestone achievements on compounds with Si=Si (West et al) [5] and Si=C bonds (Brook et al) [6], the chemistry of molecular silicon compounds has matured considerably. Especially during the first decade of the new millennium the focus has shifted from the replication of well-known carbon motifs from organic chemistry to the introduction and tolerance of functional groups.…”
