Reaction of pentacyclo[4,4,0,02,5,03,8,04,7]dec-9-ene with diethyl azodicarboxylate; synthesis of cis-9,10-dihydronaphthalene
Abstract
Treatment of pentacyclo[4,4,0,02,5,03,8,04,7]dec-9-ene with two equivalents of diethyl azodicarboxylate affords a 1 : 2 adduct which undergoes hydrolysis–decarboxylation reactions giving rise to cis-9,10-dihydronaphthalene.
