Abstract
<div class="WordSection1"><p>The thiosulfonates are a class of compounds of great industrial importance. It is worth noting that the aryl thiosulfonates present several biological activities. The synthesis of these compounds is known in the literature although; only a few make use of thiols as the sole starting material. This work shows the use of two reaction systems employed for the synthesis of nitrophenols, AgNO<sub>3</sub>/BF<sub>3</sub>.EtO<sub>2</sub> (I) and HNO<sub>3</sub>/Al(H<sub>2</sub>PO<sub>4</sub>)<sub>3 </sub>(II), as an alternative to the preparation of aryl thiosulfonates. The use of system I led to higher yields (72-76%) then system II (56-61%). These methodologies have not been reported before for the synthesis of these compounds and the products were obtained with good purity.</p></div>
