Stepwise Syntheses of o,o'-Methylene Bridged Cyclohexamers with p-Cresol and 4-tert-Butyl Phenol units. Comparison with Similarly Structured Hexanuclear Chainoligomers

Article abstract of DOI:10.1007/BF00899779

Two phenolic alcohols with six phenolic units in their molecules have been obtained by stepwise syntheses starting from simple phenolic derivatives.The phenolic alcohols were cyclized in a one step cyclization by boiling in a very diluted acetic acid solution.A two step cyclization of a phenolic alcohol with three phenolic units to a cyclohexamer proceeds only with poor yields.The cyclic compounds were compared with chainlike oligomers containing six phenolic units in their molecules. - Keywords: Chainlike phenol formaldehyde compounds; Cyclohexamers with phenolic units; Phenolic alcohols
