Bromination of α-lapachone (I) with 2 mol N-bromosuccinimide yields 3,4-dibromodehydro-α-lapachone (III), dehydro-α-lapachone (II) and 4-hydroxy-α-lapachone (IV).Dehydro-α-lapachone (II) on bromination with N-bromosuccinimide yields III and β,β-di-(bromomethyl)pyrano-1,4-naphthoquinone (VI).The formation of III and VI in the above reactions seems unusual.
