report a new method for the synthesis of acylphosphineoxides by the direct coupling of hydrogen phosphine oxides and acyl chlorides mediated by chlorosilanes. This new protocol is greener and safer, because it precludes the generation of volatile haloalkanes and the use of oxidants employed in the conventional methods. Moreover, moisture-unstable acylphosphineoxides that are difficult to prepare via the

The present invention relates to a catalyst composition for hydroformylation and a method for preparing aldehydes using the same, wherein the catalyst composition for hydroformylation comprises: a triaryl phosphine ligand; a phosphine oxide or phosphine sulfide ligand having a specific chemical formula; and a transition metal catalyst. The catalyst composition provides high catalyst activity and stability and selectivity to normal aldehydes when used in the hydroformylation for preparing aldehydes from olefins.
