An efficient synthesis of 2,6-di-tert-butylphenyl esters by palladium-catalysed carbonylation of 4-bromobiphenyl
Abstract
2,6-Di-tert-butylphenyl biphenyl-4-carboxylates were synthesized in good yields by palladium-catalysed aryloxycarbonylation of 4-bromobiphenyl with the alkali-metal 2,6-di-tert-butylphenoxides.
