✦ Synopsis

In this work is reported a method for the preparation of (R 4 N) 2 MS 4 (R =Pr, Oct and M = Mo, W) in aqueous solution. The rapid substitution of (NH 4 ) salts with [(Pro) 4 N] and [(Oct) 4 N] salts, via reaction with (Pro) 4 NBr and (Oct) 4 NBr is described. Thiomolybdates and thiotungstates characterization was performed using FT IR, UV-Vis spectroscopies and thermogravimetric analysis (TG-DTA).
