ABSTRACT:
2,2-Dialkylpropionaldehydes I ##STR1## where R.sup.1 and R.sup.2 are each C.sub.1 -C.sub.4 -alkyl, are prepared by hydroformylation of 1,1-dialkylethylenes II ##STR2## with cobalt carbonyl complexes, entailing (a) carrying out the reaction in the presence of water-containing solvents in which water is soluble or at least partially soluble, with the water content of the reaction mixture being from 0.1 to 20% by weight, or
