A new radical decarboxylation reaction for the conversion of carboxylic acids into hydrocarbons
Abstract
The esters of trans-9-hydroxy-10-phenylthio-or -10-chloro-9,10-dihydrophenanthrene are smoothly reduced under neutral conditions by tri-n-butylstannane to furnish, by radical elimination, phenanthrene and the nor-hydrocarbon formed from decomposition of the corresponding acyloxy radical.
