2-Methoxy-1,4-benzoquinone can be alkylated selectively with trialkrylboranes in position 5, giving high yields of 5-alkyl-2-methoxy-1,4- benzoquinones after oxidative work up. In the case of 2-hydroxy- 1,4naphthoquinone, the same procedure leads to 3-alkylated products. A radical chain mechanism is proposed to explain the observed selectivity.
