-6-C,N)dipalladium(II) complex that results undergoes an insertion reaction with methyl vinyl ketone, and the resultant β-aryl-α,β-unsaturated ketone is cyclised, as the methiodide, by K2CO3 in ethanol to the corresponding ethyl N,N-dimethyl-1,2,3,4-tetrahydroisoquinolinium-3-carboxylate. This sequence constitutes a new synthesis of the isoquinoline ring, with functionalised substituents at C(3) and
