Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Silicon‐oxygen doubly bonded species</bold> have received extensive attention over the past 100 years as silicon versions of carbonyl compounds. Tricoordinate diorganosilanone (R₂SiO) has been an elusive species, but S. Ishida, T. Iwamoto et al. have now reported the generation of dialkylsilanone as persistent species in solution at low temperatures by dehydrobromination of the bulky dialkylbromosilanol in the Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 15100 ff.</ext-link> The dialkylsilanone was identified by ²⁹Si NMR and IR spectroscopy and trapping reactions. This illustration displays the molecular structure of R₂SiO with its ²⁹Si NMR spectrum in solution.<graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkhm3c92g" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
