摘要:
A process for preparing bis(hydroxymethyl) compounds of the formula (I) ##STR1## wherein X.sup.1 and X.sup.2 represent identical or different electronegative groups, which process entails reacting C--H-acidic compounds of the formula (II) ##STR2## wherein X.sup.1 and X.sup.2 are as defined above, with formaldehyde, wherein the reaction is carried out in an anhydrous medium.
