Abstract
The present invention provides an improved process for the synthesis of α-substituted acroleins from olefins by a tandem hydroformylation and Mannich reaction sequence in the presence of syngas and formaldehyde, wherein the two catalysts are segregated into two different phases thereby preventing deactivation of the catalysts by each other, and yielding a highly selective and active catalyst.
