Silicon-oxygen double bonds: A stable silanone with a trigonal-planar coordinated silicon center

Abstract

Siï£O 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 N2O. Silanone 3 features a polar, short Siï£O bond (1.526(3)Å) to a trigonal-planar-coordinated silicon center and reacts with water to give the dihydroxysilyl complex. © 2014 WILEY-VCH Verlag GmbH.
