SiO in a complex: The first silanone that is stable at room temperature (3) is reported. The two-step synthesis involves carbonylation of the silylidyne complex 1 to give the chromiosilylene 2, followed by oxidation of 2 with N2 O. Silanone 3 features a polar, short SiO bond (1.526(3) Å) to a trigonal-planar-coordinated silicon center and reacts with water to give the dihydroxysilyl complex.
报道了首例室温稳定的硅烯酮（3）。两步合成法包括将甲硅烷基络合物 1 进行羰基化得到色原硅烯 2，然后用 N2O 将 2 氧化。硅烯酮 3 具有一个极性的短 SiO 键（1.526（3）Å）连接到一个三角平面配位的硅中心，并与水反应生成二羟基硅基络合物。
