Effect of Copper Ions in Organic Synthesis. Part IV. Stereospecific 1,4-Addition of Some Alcohols to Phenylazostileene in Presence of Copper and Iron Ions

Abstract

In our previous papers^1–3 some interesting effects due to copper (II) ions in organic synthesis were reported. A prelimi nary iwestifation cn the 1.4-addition of some alcohols to the szo-ene systern cfrhenyiatcstilbene showed that It was Dossi-2 leti ottain α(I-alkoxyohenylhydrazones as mixture of two synenti isopsrs wnen comer [II] sulphate nentahydrate oriron (II) sulct-ate eotahydrate was addad.
