Versuchsvorschrift
It has now been found that, by reacting 6-methoxy-2-bromonaphthalene with 3-ethylenedioxybutene (II) in the presence of a bivalent palladium salt and a phosphine, the reaction takes place extremely rapidly without operating under pressure and the 6-methoxy-2-(3-ethylenedioxybuten-1-yl)naphthalene (III) is obtained in optimum yields.
