Carbon dioxide and silicon dioxide are almost nothing alike, despite the apparent similarity of their chemical formulas. The reason is that whereas carbon forms discrete multiple bonds to oxygen, silicon tends to form networks of single bonds in an extended solid. Kobayashi et al. now report that, with the help of rather bulky aryl groups, they synthesized a silanone: a molecule with a Si=O double bond analogous to a carbon-based ketone. The compound was stable at room temperature and characterized by crystallography but dimerized head-to-tail in solution upon heating.
