A hydroformylation catalyst of the formula

Bimetallic carbonyl hydroformylation catalysts

Carbon monoxide is removed from feedstreams by a process which comprises contacting the feedstream with a solution of a cuprous fluorinated acetylacetonate in an organic solvent containing a stabilizing agent to remove CO by forming a first cuprous complex, decomposing the first cuprous complex whereby the stabilizing agent which replaces CO in the first cuprous complex to form a second cuprous complex, and separating the displaced CO. The formation of the second cuprous complex avoids any deposition of copper metal upon heating.
