Chemistry of heavy carbene analogs R2M, M = Si, Ge, Sn. IX. Properties and thermolysis of new 7-silabicyclo[2.2.1]heptadienes was written by Appler, Hubertus;Gross, Lutz W.;Mayer, Bernd;Neumann, Wilhelm P.. And the article was included in Journal of Organometallic Chemistry in 1985.Product Details of 452-62-0 This article mentions the following:
Factors governing the ease and mechanism of 7-silabicyclo[2.2.1]heptadienes thermolysis in order to generate free silylenes and the corresponding benzene derivatives are investigated. For this purpose, 29 new compounds, I–IV (R1 = Cl, Me, p-tolyl; R2 = Cl, Me, Ph, p-tolyl, R3, R4 = H, Me, Ph; R5 = H, CO2Me; R6, R7, R8, R9 = H, Me; R6 = R9 = H; R7R8 = benzo), have been prepared No indications for a polar mechanism or an intermediate biradical could be found. The degradation is 1st order in all cases investigated, and is enhanced by Ph groups at the bridgehead C atoms, if a conformation coplanar with the basic ring is allowed by the neighboring substituents, but is not enhanced by Ph groups at the Si. In the experiment, the researchers used many compounds, for example, 3-Bromo-4-fluorotoluene (cas: 452-62-0Product Details of 452-62-0).
3-Bromo-4-fluorotoluene (cas: 452-62-0) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
