Abstract
The stepwise syntheses of cyclo{quater[(5‐alkyl‐2‐hydroxy‐1,3‐phenylene)methylene]}s (5) are described and compared with a one‐flask reaction procedure. The structures of the cyclic compounds 5 are analytically confirmed and their properties were compared with those of linear phenol formaldehyde condensates which have very similar structures and molecular weights.
