Abstract
Abstract 2-Chloro-1, 4-naphthoquinones underwent palladium-catalysed cross coupling reactions with arylboronic acids to give the corresponding 2-aryl-1, 4-naphthoquinones. Similarly, 2, 3-dichloro-1, 4-naphthoquinone underwent efficient cross coupling reactions with arylboronic acids to give mono or bis adducts. The required 2-chloro-1, 4- naphthoquinones were conveniently prepared from the corresponding 2-hydroxy-1, 4- ...
