    • Process for preparing hydroxybenzaldehydes of the formula (1) ##STR1## in which R.sup.1 -R.sup.4 are hydrogen, fluorine, chlorine, bromine, alkyl, alkoxy, phenyl, naphthyl, phenylalkyl, naphthylalkyl, phenoxy or saturated or unsaturated cyclopentane or cyclohexane radicals, and R.sup.1 -R.sup.4 may with the hydroxybenzene ring carbon atoms on which they are located form 1 or 2 saturated or unsaturated isocyclic or heterocyclic rings, by admixing 1 mol of a phenol of the formula (2) ##STR2## in which R.sup.1 -R.sup.4 have the stated meanings, in a pressure vessel with from 5 to 100 mol of hydrogen fluoride and from 0.5+x to 1.5+x mol of boron trifluoride, where x is the number of oxygen atoms contained in the starting compound (formula (2)), setting the mixture to from -10.sup..degree. to 100.degree. C. and then passing carbon monoxide into this mixture until a pressure of from 10 to 150 bar is reached and allowing the mixture to react at the desired pressure reached.
