Abstract
Oxidation of p-hydroxycinnamyl alcohols together with dimeric lignin m odel compounds containing arylglycerol beta-aryl ether structures was found, under certain conditions, to yield cross coupling products with beta-aryl ether and 5,5'-biphenyl bonds. Cross coupling appeared to b e restricted to phenols of similar oxidation potential. The implicatio ns of the ''limits to randomness'' for the understanding of the lignif ication process in vascular plants are discussed.
