A study on the gegenion effect in Heck reaction of arenediazoniumsalts has given rise to arenediazonium perchlorates and fluorides as alternate Heck-substrates to the tetrafluoroborate salts.

reactions were carried out in water at room temperature under mild and heterogeneous conditions. Moreover, temperature dependent NMR spectra were studied for 1-(2-nitrophenyl)-3,3-diethyltriazene to determine the rotational barrier energy around N(2)–N(3) bond of this molecule. Simple and clean work-up, short reaction times and good yields were the advantages of this method.
