OH I OH CH i nærværelse af katalytiske mængder af mindst en uorganiskeller organisk sur forbindelse ved en høj temperatur, idet produkterne fra omlejringen fjernes fra reaktionsblandingen efterhånden som de dannes. 1,l-bis(2-hydroxybenzen)alkyl- og/eller -arylethan opnås ud fra substituerede phenoler og aldehyder under indflydelse af specielle katalysatorer.

Endvidere omfattes 1,l-bis(2,3-dihydroxybenzen}alky1-eller -aryl-methan med formlen: F?2 R2

OH I OH

R hvori R betegner ligekædet eller forgrenet alkyl eller aryl;

Rj, R2 og R3 er ens eller forskellige og betegner H, halogen, ligekædet eller forgrenet alkyl, aryl, alkaryl, -OH, -OR4, -N(R4)2* hvori R4 betegner ligekædet eller forgrenet alkyl. Sådanne forbindelser opnås ved omsætning af en diphenol med formlen:
