Abstract
The thermal reaction of methyl 2-oxo-2H-pyran-5-carboxylates with subs tituted styrenes in the presence of 10% palladium on activated carbon afforded directly the corresponding methyl 4-biphenylcarboxylates in g ood yields. By the similar procedure, methyl 4-heteroaryl- and 4-alkyl -substituted benzoates were obtained from heteroaromatic olefins and a lkenes, respectively.
