The example of diethylene glycol diacrylate was used to demonstrate the possibility of thiocyanatoarylation both by one and by two multiple bonds of compounds with two isolated multiple bonds. The reactions of arenediazonium tetrafluoroborates with diethylene glycol diacrylate in aqueous acetone (1:2) in the presence of catalytic amounts of copper gave 1-acryloyloxy-2-[2-(2-thiocyanato-3-arylpropionyloxy)ethoxy]ethanes. The latter were reacted with arenediazonium tetrafluoroborates in aqueous acetone (1:3) to obtain 1-[2-(2-thiocyanato-3-arylpropionyloxy)ethoxy]-2-(2-thiocyanato-3-arylpropionyloxy)ethanes via thiocyanatoarylation by two multiple bonds.
