Disclosed is a method for the producingtiona target compoundby oxidative coupling of methane. A starting gas mixture is provided which contains an olefin, carbon monoxide, carbon dioxide and optionally hydrogen, wherein the olefin is subjected to hydroformylation with the carbon monoxide and the hydrogen of the starting mixture to obtain an aldehyde, wherein the paraffin and the olefin have a carbon chain with a first carbon number and the aldehyde has a carbon chain with a second carbon number which is greater by one than the first carbon number. The carbon dioxide present in the starting mixture is removed upstream and/or downstream of the hydroformylation. The carbon dioxide is subjected to dry reforming with methane to obtain carbon monoxide, and that the carbon monoxide subjected to hydroformylation comprises at least part of the carbon monoxide obtained in the dry reforming .
