Tert.-butoxybutanals and tert.-butoxybutanols (I) and bis-tert.-butoxypentanals and bis-tert.-butoxypentanols (II) ##STR1## where R.sup.1 and R.sup.2 are H or C.sub.1 -C.sub.4 -alkyl, one X is --CHO or --CH.sub.2 OH and the others are H. These compounds, which are valuable as fragrances and for use in organic syntheses are obtained by hydro-formylating the ethers (III) and bis-ethers (IV), respectively, using Rh catalysts. ##STR2##
