Abstract. The reaction of a number of aldehydes and ketones with 1,3-propanedithiol has been carried out in the absence of solvent,
using microwave irradiation as the heat source. Under these conditions the corresponding 1,3-dithianes were obtained in short reaction times (5 min). In addition, a bentonitic clay was evaluated as promoter of this reaction.
Resumen. La reacción entre varios aldehídos y cetonas con 1,3- propanditiol se llevo a cabo en la ausencia de disolvente, utilizando
irradiación de microondas como fuente de calor. Bajo estas condiciones, se obtuvieron los correspondientes 1,3-ditianos, en tiempos
cortos de reacción (5 min). Complementariamente, se evaluó la capacidad de una arcilla bentonitíca como promotora de esta reacción.
