A novel palladium-catalyseddirectarylation of guaiazulenes with a variety of arylbromides is reported. Both sp(2) and sp(3) C-H bonds have been functionalised, as the nature of the cation of the base was found to allow the control of the regioselectivity of the arylation giving rise to C2 or C3 arylated guaiazulenes and also to 4-benzylguaiazulenes.
