The present invention concerns a method for the hydrosilylation of an unsaturated compound comprising at least one ketone function, one aldehyde function, one alkene function and/or one alkyne function, with a compound comprising at least one hydrogen-silyl function implementing an organic catalyst of tri-coordinated germanium.

The synthesis of the first isolable C-phosphino-Ge-aminogermyne, stabilized by a phosphine ligand, has been achieved. X-ray diffraction analysis indicates a quite long Ge-C bond whose length is between that of a single and a double bond but consistent with the theoretically predicted values for a germyne bearing π-donating substituents. The isomerization of this germyne derivative affords a new stable

complex [Rh2(μ-Cl)2(COD)2] leads to the corresponding phosphine–germylene–Rh(I) complexes (2a,b). Interestingly, the stability of these complexes depends strongly on the nature of the substituent of the germylene fragment. Indeed, the complex (2a) with the chloro-germylene ligand isomerizes into a metallacycle rhodium complex (3a) via germylene insertion into the Rh–Cl bond, while the complex with the phenyl-substituted
