It was found that lanthanum metal caused the dehalogenation of o-dihalogen substituted arenes and a,a 0 -dihalogen substituted o-xylenes to generate the corresponding benzynes and o-quinodimethanes. When o-dihalogen substituted arenes were allowed to react with lanthanum metal in the presence of die
A detailed inspection of phenolic oxidation products derived from the o,o'-dihalogenated cresol derivatives (la -le) indicated that the bromo and chloro substituents promoted the oxidation leading to the corresponding diaryl ethers, whereas the iodo derivatives provided the diaryls. Selective reduct
