摘要

Bis-tert.-butoxypentanals and bis-tert.butoxypentanols of the formula ##STR1## where R.sup.1 and R.sup.2 are H or C.sub.1 to C.sub.4 alkyl, one X is --CHO or --CH.sub.2 OH and the others are H.P PThese compounds, which are valuable as fragrances and for use in organic syntheses are obtained by carrying out a catalytic hydroformylation, using a rhodium catalyst, of a bis-ether of the formula ##STR2##
